--picstats is the default when compiling the .pic version of an application.

This seems like a fine way to profile vortex. You probably don't need to
compile as big an application as vortex itself, but it doesn't hurt.
You can look at $VORTEX_HOME/Cecil/bin/shell/make-profile to see how we gather
profiles of vortex. We also use this script as a kind of exerciser test, so it
does more work than it has to just to gather reasonable profile data.
