su no longer working after dist-upgrade

[Marc D Chapman <chap0084@tc.umn.edu>]

Recently I performed a apt-get dist-upgrade on my potato box.  Since then
whenever I 'su' I am unable to do anything from the shell prompt.  It
always gives me an error like:

	bash: fork:  Resource temporarily unavailable

This makes life extremely more difficult for the purpose of upgrading
without logging out.  Has anybody else had this problem?  Any ideas as to
why this is happening, or how to fix it?  TIA....
