Forgot to mention that I know about Dossy's comment in the wiki that
nsv_incr can be used to this effect, and I'm doing that.

but I was wondering why "try" wasn't part of ns_mutex when the C code
is there for it.

In the C code, there's a Ns_MutexTryLock() function, but no tcl
function for calling it.
Ns_MutexLock calls Ns_MutexTryLock() and there appears to be
timeout support:
if (!NsLockTry(mutexPtr->lock)) {
return NS_TIMEOUT;
}
but I don't see any way of setting the mutex timeout seconds.
It's trivially simple to modify NsTclMutexObjCmd (in tclthread.c)
to support "ns_mutex try" and I'm wondering if there's a reason
this hasn't been done.
