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.
