>Description:
From work on OpenAFS, fileserver receives SIGQUIT, but sigwait never
cleans up and exits. This is beause sigwait doesn't get signals from
pthread_kill.
>How-To-Repeat:
pkgsrc/net/openafs
src/util/softsig.c:
"bos restart fileserver"
>Fix:
comment from softsig.c:
/*------------------------------------------------------------------------
* Under Darwin 6.x (including 7.0), sigwait() is broken, so we use
* sigsuspend() instead. We also don't block signals we don't know
* about, so they should kill us, rather than us returning zero status.
*------------------------------------------------------------------------*/
setting the same defines as for Darwin make things work correctly.
