On a clean shutdown, the process should clean up its lock files; if it
isn't, that needs to looked at and/or reported.  The only caveat to
that I'm aware of is if a debug flag is set, files the process uses
may be intentionally left behind.  However, it doesn't sound like you
would be setting such flags.

Windows .bat/.cmd files, custom crafted shortcut on the desktop,
windows registry changes... depends on the situation.  The one I
referenced with the dumb terminals and flaky power is a registry call
in autorun starting a .cmd file.

My apologies; I was only considering kill -9 as 'kill the process'.
You are correct, kill -15 is also a kill, but should allow the process
to exit cleanly.

I will certainly agree that shutting down X cleanly should not leave
stray lock files behind.  I can also say that I'm not experiencing
that issue.  My best guess (and this is only a guess) is that
something is causing X to crash as it shuts down on your system,
causing the lock files to be left behind.
