* gthreadpool.c (g_thread_pool_thread_proxy): Until now every
thread pool always had at least one tread waiting to avoid
switching overhead in case a new task would be added soon after
one finished. This however means a big waste of threads, if many
mostly inactive thread pools are involved. Now such a waiting
thread will only wait for half a second (This value is of course
very randomly picked) and go to the global threadpool afterwards.
MCVS: ----------------------------------------------------------------------

* gthreadpool.c: Added documentation.
* gthreadpool.c: The global thread pool now also is seperated for
bound and unbound threads. Only threads with standard stack size
go to the global pool. g_thread_pool_new now protects the global
setup of inform_mutex etc. with a lock. Fixed some typos. Unlock
the queue after g_thread_pool_wakeup_and_stop_all in the proxy.

* configure.in: Add a surrogate for thread priorities using PID
niceness for systems with no thread priorities and different PIDs
for threads of the same process (most notably: Linux). Define
G_THREAD_USE_PID_SURROGATE in that case, as used by
gthread-posix.c. Also make the system thread bigger by
sizeof (long) to contain the thread's PID.
* gfileutils.c: Include stdlib.h for mkstemp prototype.
* gthread.c: Add priority range checks to the affected functions.
* gthreadpool.c: Remove unused variable.
* gthread-impl.c, gthread-posix.c, gthread-solaris.c: Removed
g_thread_map_priority function in favour of the
g_thread_priority_map array. Initialize the array with
PRIORITY_{...}_VALUE, if available and interpolate beetween the
bounds if .._NORMAL_.. and .._HIGH_.. are not available.
* gthread-posix.c: If we should use the PID niceness as a
surrogate for thread priorities (G_THREAD_USE_PID_SURROGATE is
defined), then disable normal priority handling and use PIDs and
setpriority() instead. Depends on the thread to write its PID into
the place after the thread id right after thread creation.

* gthreadpool.c: Don't take threads with other priorities into
account as changing the priority is highly unportable. (Actually
using it at all already is unportable, but even sometimes where
that works, changing priority is not possible).
2000-09-01 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* glib.h: Include gerror.h before it is used for some g_thread_*
functions.
* gthread.c, gthreadpool.c, glib.h: Enable error reporting for
thread creation, namly for g_thread_create, g_thread_pool_new,
g_thread_pool_push and g_thread_pool_set_max_threads.
* tests/thread-test.c, tests/threadpool-test.c: Adapted
accordingly.
* gthread-posix.c (g_thread_create_posix_impl): Use GError to
report errors.

* *.[hc]: applied patch from Andreas Persenius <ndap@swipnet.se> that
updates the license headers to the GNU Lesser General Public License,
as well as updating the copyright year to 2000.
2000-04-28 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
* gasyncqueue.c: New File implementing an asynchronous queue to be
used for asynchronous inter-thread communication.
* gthreadpool.c: New File implementing a thread pool to be used
for distributing work among several threads.
* glib.h: Added the type and function declarations for these two
types.
* tests/threadpool-test.c: New File implementing a test for the
thread pool. This also checks the asynchronous queue underlying
the thread pool.
* tests/Makefile.am: Changed accordingly.
