As root:
# su `perl -e 'print "A" x 100000000'`
bash: /bin/su: Argument list too long

This is on a Celeron 333 w/384MB of physical RAM.  Red Hat 7.1 It took 
about a minute and a half to come back, and top says that
bash was using 415MB of memory.  

I suspect you're just beating the crap out of swap, and need more RAM
or process limits.
