Profiling in 4.1 (was: MessageTally problems)

Thanks for your help. Is it theoretically possible for the VM to be
told by the image, just before a profile starts, "turn on the
timer-checking" and then, after the profile, don't?

Profiling is such an important tool for performance. Is there any way
we can both have and eat cake?
