CVS commit: src/lib/librumpuser

Module Name:    src
Committed By:   pooka
Date:           Mon Nov 29 11:40:55 UTC 2010

Modified Files:
        src/lib/librumpuser: rumpuser_sp.c

Log Message:
Cache syscall worker threads and include some stetson-harrison
limits.  This improves syscall throughput about 2x for non-userio
syscalls (no copyin/out, e.g. getpid()) and almost 1.5x even for
things like __sysctl().
(measured for cases where the remote process is on the local machine)

XXX: if the pthread deadqueue sucks for anything which cares about
performance, why does it exist?  Nuking it would make supporting
variable stack size easier.
