remove_pidfile is not atomic

[pho-enix]

def remove_pidfile File.unlink(self.pidpath) if self.pidfile_exists? end

No such file or directory @ unlink_internal - /tmp/a.pid

Looks like this is a race, and the pidfile disappears right after the exists has been runt.

I think either the check and delete should be flocked or the delete should not fail if the file is not there.

Thanks, Sebastian, but I haven't worked on this for years.

Feel free to fork it and make it work correctly.
