Basically there's a chance of it leaking memory by mistaking a data word
for a pointer.  This is unlikely to happen by accident and usually
inconsequential if it does happen, but maybe there could be malicious
data that makes it happen

Also, it's a non-compacting gc that has to touch all the garbage as it
sweeps, not a reliability issue per se, but not great for performance
especially in large, long-running systems.

It's brilliant though.  It's one of those things that seemingly can't
possibly work, but it turns out to be quite effective.
