How do you programmatically detect if a gnu process is still alive?
On other Unix's I have performed some of the following,

: Performed a popen of the command "ps -p 12345" and read the output.
(Won't easily work for gnu-win32).

: sent a kill -SIGUSR1 to the process, and check for an error coming
back (have to be same user).

: Looked for a directory in /proc (for Linux/svr4 Unixes, but not
gnu-win32).

: Read the kernel memory (hairy coding!).

What would be the best way to do this under gnu-win32?
