This is where you're mistaken.	Some browsers (Firefox?) have one thread for
all pages.  They cannot support two threads both accessing DOMs, even
different
DOMs, because their implementation is not thread-safe at all.  Different pages

can both access DOMs because they're actually on the same thread.

(I think.)

---------
You may be right about the single thread.  Also it appears that Firefox does
not allow one to start another instance of it as another process.  Even with 3
running, there is only a single firefox in the process list.

In such a situation, I would recommend that Firefox be changed rather than the
spec.
