That's good because the patch as written is a big security hole (and in
fact will not work on any systems with SMAP enabled)

The basic concept seems reasonable, although a single address may be
too inflexible.

Often the main request I hear is for a simple way for an application
to turn on/off profiling, and perhaps add markers to distinguish
phases. It many cases that may be good enough.
