I tried ulimit in bash 0.99 on a uVaxII running Ultrix 2.0.

bash> ulimit -s 
I get a message telling my current maximum stack size.
bash> ulimit -s 1000000000
bad ulimit
bash> ulimit -s 100000000  		no message
bash> ulimit -s
-663296					!!!!!!
bash> ulimit -s 32000
bad ulimit
bash> ulimit -s 2048
bad ulimit

basically, once I have set ulimit to 100000000, I can never reset it.
If I try to start a sub-bash now, it just core dumps with an illegal
instruction.  Some programs die now, some don't.  (ls, sh survive, csh
dies).

Also a suggestion: ulimit should provide some idea of what the maximum
setting is for a particular resource, or have a keyword 'unlimited' as
in csh, so we don't have to worry about it.
