-Subject: [PATCH] Only use available CPUs
-
-Not all online CPUs may be available for the current process,
-especially when CPU affinity is involved. In such cases too many
-threads will be created, which will then compete unnecessarily
-for CPU time.
-
-Use sched_getaffinity() to determine the correct number of threads
-to create.

-Subject: [PATCH] Don't use sigwaitinfo()/sigtimedwait() if not supported
-
-If sigwaitinfo() and sigtimedwait() are not supported,
-use sigwait() instead.
-
-This will disable the queue/caches dump if ^\ (SIGQUIT)
-is hit twice within a second.
-
-But the queue/caches dump is still available if SIGHUP
-is sent to the program.
-
-Currently this check is applied to MAC OS X.  FreeBSD and
-NetBSD appear to have these functions.
