We don't want this generally.  It's trivial to imlement this kind of
thing using gcc mcount instrumentation, but no one managed to submit
a generic implementation of this yet.  acme is hacking on some cool
tools to make similar things possible.  acme, any chance you might
have a cool idea about something based on ostra that we could merge
to allow people to do this without messing up the source code [1].

[1] yes, the l33t crowd would call this aspect oriented programming,
	I'd cool this cool and useful tool :)
