Subject: GC in MRI 1.9 and REE

Hi all,

While playing with the GC in different ruby implementations i've got a
pretty  odd  situation with MRI GC.

here is the code i've used with the results -
https://gist.github.com/1589617

If i understand correctly the both implementations(MRI and REE) uses the
same GC strategy - mark and sweep.

The problem is that the MRI is not deallocating objects after the
reference is removed.
I'm not certain is it a bug or I misunderstood some GC concepts.

PS: The allocations are confirmed with vmmap tool so it's not an live
objects calculation problem.
