Subject: Don't need to worry about catching too many signals since we do locking
X-Git-Tag: SUDO_1_6_0~75
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8fcdf8a30020328396f10e2d79acc09eec25efdc;p=sudo

Don't need to worry about catching too many signals since we do locking
on the tmp file.  If a lockfile is really stale, it will be detected
and overwritten.
