I'd invite you to try it.  It's an *extremely* useful tool for finding
memory allocation an access problems.

It also has a companion tool helgrind which looks at threading and locking.

This is the purpose.

There are already compile time conditions to do this (which I've been
using).  If you're talking about runtime conditions, this is of course
doable.  Patches welcomed :)

I'd like both options if I could have them.  I just think the valgrind
instrumentation is more useful.
