Bert Belder 4e53af9120 win,pipe: fix IPC pipe deadlock ... This fixes a bug where IPC pipe communication would deadlock when both ends of the pipe are written to simultaneously, and the kernel pipe buffer has already been filled up by earlier writes. The root cause of the deadlock is that, while writes to an IPC pipe are generally asynchronous, the IPC frame header is written synchronously. So when both ends of the pipe are sending a frame header at the same time, neither will read data off the pipe, causing both header writes to block indefinitely. Additionally, this patch somewhat reduces the spaghetti level in win/pipe.c.
