* tests/refcount/closures.c: test high contention on closure
reference counts to trigger and catch non-atomic updates.
* tests/refcount/objects.c:
* tests/refcount/objects2.c:
* tests/refcount/properties.c:
* tests/refcount/properties2.c:
* tests/refcount/signals.c:
fixed up test and threading fundamentals. variables accessed from all
threads need to be volatile. context switches are enforced by using
g_thread_yield(), not g_usleep(1) which may result in busy waits on
some platforms. for testcode, always consider all warnings and
critical messages fatal. issue the currently running program on
stdout. improved progress indicators.
* tests/refcount/properties.c:
* tests/refcount/objects.c:
don't overdo the number of testing threads to keep the testing machine
usable, 2 threads can produce as much contention as 20 if executing the
same code.
* tests/refcount/signals.c: only start 1 thread per object. GObject
doesn't provide mutually exclusive object access, but only mutually
exclusive reference count modification.
* tests/Makefile.am: added closures test.
