Compatibility observation

[greg andruk]

I should mention I found a compatibility quirk between Python 2.0 and
INN while testing the patch I just sent in.

Python 2.0's garbage collection does something weird that can cause
INN to segfault in glibc's malloc().  I'm afraid I don't have time to
track down why this happens, but the problem can be avoided by
building Python --without-cycle-gc .  This probably also applies to
1.6, but use of that release is discouraged anyway.

This should probably be documented, but I'm not sure where.
