Summary: Killing grandchildren?

Initial Comment:
I am trying to spawn, then kill, a gem_server process.  On windows, however,
this actually spawns a child cmd instance for the gem_installer.bat file, which
then spawns a grandchild ruby process for the gem_server command.

I can''t figure out how to make the grandchild process die.  If I could
get it''s PID, I could kill it, but I only have the pid of the child
process.  If I kill the child, then the grandchild is not killed, but stays
alive, and is owned by the top-level cmd shell process.

Here''s the file where I am trying to do this:

Thanks,
Chad

Message:
There''s just no way to do that as far as I know, because of the way the
Windows process model works, i.e. Processes know about their children but not
their grandchildren.

However, since it appears that you''re trying to daemonize a gem_server,
I recommed using the ruby-services package. It has services for gems, webrick
and fastri. Install the gem service, and control it that way instead.
It''s what I do.

Regards,

Dan
