Really? We've found that gprof, for instance, doesn't exactly have
"zero interaction with the rest of the backend" --- there's actually
a couple of different bits in there to help it along, including a
behavioral change during shutdown. I rather doubt that Perl profilers
would turn out much different.
But in any case, I don't believe for a moment that profiling is the only
or even the largest use to which people would try to put this.
