They're now compiled under 9.0-S with just:
-O2 -pthread
libc_r is a user mode implementation of pthreads, so there is one actual
kernel thread with a stack. You now have ~700 kernel threads on startup.
Per-thread stack allocation will be different, and you could quite easily
explain differences that way.
That seems the most fitting explanation so far - aside from seeing if I can
cut back on the number of threads, I presume there's no "issue" with having
that many kicking around - the RES size is still quite 'small' (still
waiting to see if anything is 'leaking') - and if ~700 threads happily ran
under user mode pthreads - it should still perform at least 'similarly'
with kernel threading?
