This change gets rsync working without any warning or errors. On Windows we now create a bunch of C:\var\sig\x\y.pid shared memory files, so sigs can be delivered between processes. WinMain() creates this file when the process starts. If the program links signaling system calls then we make a thread at startup too, which allows asynchronous delivery each quantum and cancelation points can spot these signals potentially faster on wait See #1240
