[IronPython] Interlocked methods and IronPython

[Dan Eloff]

... sometimes. The reason it seems to work is that python integers are
immutable and the safe count is always zero :) You could assign back
to SafeCount the result of the increment, but the assignment isn't
necessarily safe. I guess these kinds of things either need to be
written in C#, or use a Monitor or Lock as always in Python.
