  You can't kill a windows process with cygwin kill.  Presumably your software
is using the windows native functions to spawn child processes?  That's not
necessary: cygwin gives you unix syscalls on windows.  If you used the standard
posix functions (fork/exec/etc) to start the children, kill would work fine on
them, and you'd have a lot more common code and a lot less differences to keep
track of between your unix and 'doze versions of your code.

    cheers,
