Just for fun, I tried this on VMS compiling under cxx 6.2 and I'm seeing
similar results.  My virtual page count grows while threads are being
created until the process finally exits with:

    omni_thread::create raised an exception

It looks like it will create 3361 threads before it crashes.  However, it
doesn't appear to me to be running out of memory.  The page count never
gets anywhere near my quota.

I too would be interested to know what's going on here as I'd like to know
what kind of limitations I will run into if I try allocating large numbers
of threads.
