Subject: [PATCH] lockfile: reset the correct signal

From: Clemens Buchacher <[email-masked]>
Date: Mon, 26 May 2008 21:35:13 +0200

In the function remove_lock_file_on_signal(), the signal handler
for SIGINT was reset, ignoring the parameter signo.

This did not pose a problem yet, as remove_lock_file_on_signal()
was only registered as a SIGINT handler.

Thank you for fixing that.

I also realized that using signals like that can cause races. Shouldn't we
use sigaction() instead of signal()?
