Overhaul Windows signal handling
The new asynchronous signal delivery technique is now also being used
for tkill(), raise(), etc. Many subtle issues have been addresesd. We
now signal handling on Windows that's remarkably similar to the POSIX
behaviors. However that's just across threads. We're lacking a way to
have the signal semantics work well, across multiple WIN32 processes.
