I was running the Linux Test Project's latest testsuite against 2.4.7-ac1 and 
noticed one test failed that did not fail in 2.4.7 and 2.4.6-ac5.  The 
pth_str02 test (simple test that tries to create 1000 threads) could only 
make it up to 980 threads on my machine.  Saw this change in fork.c with 
2.4.7-ac1:

-       max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 2;
+       max_threads = mempages / (THREAD_SIZE/PAGE_SIZE) / 16;

Any reason why this was done?  I think the max I was ever able to hit before 
was somewhere around 1018 or so, so it's not that big of a drop.  I was just 
wondering why it was being further limited since I didn't see anything in the 
changelog about it.

Thanks,
Paul Larson
