New File implementing an asynchronous queue to be used for asynchronous

Browse Source 
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.
