I've heard from a few friends that MutVars, TVars, etc. are more
challenging for the garbage collector. I'm writing to ask if someone can
answer: 1. Is this true, and 2: Why? I can't seem to find anything like a
writeup or documentation that mentions this. The HeapObjects trac page also
mentions nothing about these supposed difficulties that GC faces with
mutable heap objects.
