Module Name: src
Committed By: apb
Date: Fri Mar 8 08:48:38 UTC 2013
Modified Files:
src/sys/kern: sys_sig.c
Log Message:
In the timeout passed to sigtimedwait, NULL means an infinite timeout,
and {.tv_sec = 0, .tv_nsec=0} means do not block at all. Add a comment
saying so. The code incorrectly treats them both as an infinite timeout,
and that is not fixed by this commit.
