	* Completely rewrote the handle waiting code: removed the helper
	thread and its attendant complexity.  All handle waiting is now
	abstracted into the WaitForSingleObject() and
	WaitForMultipleObjects() functions.

	* Implemented inter-process sharing of handles using sysv shared
	memory.  This makes handles even more opaque, with a handle now
	just an index into an array.

	* socket-io.c: Cope with SOCKET being an integer rather than a
	pointer now.

	* threads.c: Added Thread_free_internal, to deal with thread
	handle cleanup.  Moved calls to handle_store() and handle_remove()
	to start_wrapper(), so each can only be called once.  Allocate
	synchronisation blocks with GC_malloc(), and use GC finalisation
	to close the handles.

	* icall.c: added System.Threading.Thread::Thread_free_internal

	* acconfig.h:
	* configure.in: Added option to disable using shared memory for
	handles

	* shmdel.c:
	* scratch.c:
	* hps.c:
	* Makefile.am: Some tools to help debug shared memory handles:
	'hps' shows handle status, 'scratch' displays info about scratch
	data (such as handle names), 'shmdel' deletes the shared memory
	segment.

	* interp.c: Tell glib to not abort when g_log() etc print
	recursively
