WeakRefList (was Re: GC.disable not working?)

From: Eric Mahurin <eric_mahurin@...>
Date: 2005-06-20 23:35:00 UTC
List: ruby-talk #145969
I think I finally figured out a solution to making a set/list
of "WeakRef"s.  The code is below.  It mimics much of the Set
interface.  This is an order of magnitude faster than (and less
memory) using WeakRef to implement this.

The main thing I was missing was to check to see if the object
was finalized after a successful _id2ref.  If it was finalized
that means I got an object that reclaimed the space my old
object had.

I wasn't sure that you could delete elements of a hash while
iterating over it, but it looks to work fine.  Should this be
OK?  Anybody see any race conditions or other problems with
this?
