This is intentional.  Unlike the unix-ish system(), win32 system()
returns immediately to the calling process and does not wait for the
spawned process to exit.  This does not work for GnuPG since we need
to know when the child process exited and what its return code was.
Hence the CreateProcess call.

I'm not against it, but not that interested in writing it myself ;)

The mailto keyserver helper has always been a bit of a lower
priority.  I was surprised to see your mail, actually.  I didn't think
anyone was using it.

Anyone have any ideas on this one?  Is there some win32 shell magic
that can be used to associate gpgkeys_mailto with a perl interpreter?

I'd like more information about this.  Can you give me a pointer?
