Sometimes, particularly with large clipboard pastes to Windows, we could end up waiting for the timeout to expire, rather than pasting the data. Various changes to improve reliability: 1. Use XFlush() not XSync() in winProcessXEventsTimeout(). It makes no sense to ensure we have received replies to outstanding requests if we are going to wait for them using select() 2. Add XFlush() to winClipboardProc() Make sure we have sent any requests before we wait using select() 3. Don't use FD_ISSET() to check which fd is ready This looks like a Cygwin select() bug in that it sometimes returns 0 with an empty fd set before the timeout expires, but a fd appears to be ready. Add select() return value to debug output when we are warning that this has happened. 4. Drain event queues before entering select() Unconditionally drain event queues before entering select(). This seems to be the recommended way of writing select() and X event processing loops. winClipboardFlushXEvents() checks using XPending(), and winClipboardFlushWindowsMessageQueue() checks using PeekMessage() so this is safe against blocking, but means that may not need to enter select() at all sometimes.
