Kyle J. McKay c92b1762ba [core] truncate pidfile on exit (fixes #2695) 
If the server has changed its uid or is running in a chroot
it may be unable to remove the pid file when it exits.

However, if it holds on to an open handle to the pid file
that has write permission, it will be able to truncate the
pid file to 0 bytes in length.

Most monitoring software recognizes a 0-length pid file
as indicating there is no process running.

Therefore always attempt to truncate the pid file before
trying to remove it so that it's not left containing the
pid of a process that is no longer running.
