I'm confused here. My understanding of the difference between
PARROT_ASSERT and the PARROT_ASSERT_POINTER suggestion is that the

A pointer of 0 is always, 100% of the time invalid. Always.
A pointer of 0xdeadbeef has a non-zero chance of being valid and thus
throwing a false positive. We don't get to control what malloc throws
our way.
Although, I guess, we DO get to if we force all our allocations to go
through mem_sys_allocate(), which we are indeed doing. Usually. I
guess we COULD just make mem_sys_allocate() re-malloc if it gets the
magic 0xdeadbeef. Hmmm.
