What's changed in su/bash? "bash: fork: Resource temporarily unavailable"

["Oliver Elphick" <olly@lfix.co.uk>]

If I su, I then get the message "bash: fork: Resource temporarily unavailable"
on almost every command I try.

I found that `exec sh' let me do things.  So it seems that something has
changed in the set-up of bash or su
