Yes and no.
The default dispatch loop shouldn't check. The Safe dispatch loop (note the
caps there... :) should check.
Checking is more than just a plain safety issue. There are resource checks,
different jump op functions, and a variety of disabled or paranoid things
in there.
It's a non-trivial problem, but it is one that we should, and must, address
at some point. I hadn't planned on doing it so soon, but if someone's so
inclined, that'd be great. :)
