linuxthreads & linux kernel 2.4.1

[toertel]

I am having difficulty building glibc-2.2.2 with linuxthreads.  The build works
completely, however in running the check, linuxthreads failed.
I did some investigation and found that mmap was failing with ENOMEM. I hacked
__pthread_max_stacksize to be 0x003fffff, rather than the original 0x7fffffff 
(based on rlim_cur).
This seemed to fix a portion of my difficulties, i.e. some of the tests ran, but
some now fail with a core dump, and I am not sure gdb has given me anything 
meaningful.

I'm not convinced that it's a linuxthreads bug, but I thought
I'd ask.

Any suggestions, either a fix, or suggestions for debugging this further?

Thanks, Tim
