Nah, reset the allocator every time item 0 is asked for.  I'd have to
admit I haven't read Huaiyu Zhu's proposal carefully enough to be sure
this would work, but something like this ought to be possible, I'd
have thought.

I mean,

l = range(10)
for i in l:
   # do some stuff
for i in l:
   # do some other stuff

will have to do something along these lines, no?

Cheers,
M.
