I think you might have misunderstood the problem, like I originally did.

I am **********  NOT  *********** filling the system with false pointers.
See David Simcha's comment in response to mine:

It's inherently defective -- I'm merely _allocating_ a lot of memory, that's
all. The rest is a problem with the GC's algorithm.
(Unless you expect that no one will allocate one 20-MB chunk of RAM?)

I marked it as "remind", since I'm sorta reminding about this bug... if that's
not the implied meaning then my bad, but this still needs to be fixed.
