* Source/win32/GSFileHandleWin32.m: Fix background reading of pipes.
Several changes for Openstep compatiblity: Don't queue notification,
don't raise exception when asked to read while a background operation
is in progress.
* Source/win32/GSRunLoopCtxt.m: If there are no handles to block on
but there is a timer, sleep until the timer needs to wake up.
