Description of problem:
Setting a shell stack limit of 'unlimited' gives a (small) finite hardcoded 
stacksize from the pthread initialization, but setting a particular value that 
can be quite large honors the setting and gives you that value.  This appears 
very counter-intuitive to users. Could 'unlimited' be set to mean really 
unlimited, or at least very very large.

Having stack limit set to unlimited is pretty common and this would mean
no threads. 8MB is not that small (sufficient for most threaded apps) and
you can have reasonable amount of threads created at the same time.
If an application has special requirements (be it lots of threads with small
stacks or just a few stack hungry threads), you can always setrlimit before
first pthread_create call.
