Broadcast the condition, if there are waiting readers, as all might read

Browse Source 
2001-01-29  Sebastian Wilhelmi  <wilhelmi@ira.uka.de>

	* gthread.c: Broadcast the condition, if there are waiting
	readers, as all might read at the same time. Only signal the
	writer thread, if there are no more readers.

	* gthread/gthread-impl.c (g_mutex_free_errorcheck_impl): Add
        new check to errorcheck mutexes to abort, if a locked mutex is freed.
