Naive T question

[converse@anubis.uchicago.edu (Tim Converse)]

        I'm using T on an Apollo, and would like to be measuring
the CPU time used by various function calls.  Anybody know of a 
way to do this?   I imagine there's some way to do this using
DEFINE-FOREIGN, but I don't know what the system call itself
would look like.
