The idea is to have a single linked list. When GC happens we remove the

VisitWeakList
and WeakListVisitor. This means that the Map/Set does not keep the
iterator
alive but the iterator keeps the Map/Set alive which is a requirement. I
took
some rough notes when I looked at this last time:
https://docs.google.com/a/google.com/document/d/1-v25eMlmIJFdeAlYEziSV0VXI9QWUSWbdz6tuE-A22o/edit#heading=h.e03fz1pee5xt
Off-hand this sounds plausible, although it looks like it would be
duplicating
machinery that ObjectHashTable already provides. Also, if possible, it
would be
great if we found a solution that would allow self-hosting the iterator
implementation.
This was done as a seperate file because iterators depends on Symbol
which we
are not shipping and no other browser has implemented. Since everyone
else is
shipping Map and Set I didn't want to gate Map and Set on Symbols.
Symbols will be the next thing we stage, so I wouldn't worry about that.
(Where
does it currently use symbols, btw?)
