[IronPython] Mono and CollectionCount

[Sanghyeon Seo]

Dear IronPython users on Mono,

If you get an error similar to this:

Traceback (most recent call last):
File mscorlib, line unknown, in CollectionCount
NotImplementedError: The requested feature is not implemented.

Please upgrade to Mono 1.2.1 or better. Mono versions below 1.2 will
suffer this. I can't pinpoint exact conditions to reproduce this, but
it tends to happen if I try to do some complex things.

To IronPython team: where in IronPython is this feature
(CollectionCount) used, and for what purposes?
