This is a bad idea and I want to reject it outright.  No ordinary user
is really going to care about those details, and palloc is a
sufficiently hot hot-spot that even the allegedly negligible overhead
of an inactive dtrace probe is going to cost us.

If this goes in, I will disable dtrace support in Red Hat's builds,
and I rather imagine that other packagers will react similarly.
