Marcus,

Sorry, I haven't read your remark carefully enough...

Yes, on UNIX this waitpid will return immediately with ECHILD errno, but 
it was added for Win32 benefit since it does not use double-fork. I know 
that Win32 does not have kill implemented yet but when it does this 
waitpid will come handy. :o)

The patch intent is to send the spawn gpg process a signal which is a 
little bit more substantial than closed pipes.

Cheers,
Igor
