Ok, right. I tried on 3.8.1.

Can you tell us which ones? I just found one and it does not seem to
send #pushBack: to XMLTokeniser but to Stream.

If this was the case, do you think we will bother asking the mailing
list? What we are doing is:

- implementing a completely new Stream hierarchy which can work along
with the current one. It's named Nile and there has been some
announcements on this list about it.
- implementing a lot of unit tests for the current Squeak hierarchy and Nile.
- slowly studying all of the methods of the Stream hierarchy to find
which one are useful, which one are buggy...
- writing fixes to improve the current hierarchy (see the 3.10 mailing
list archive and bugs.squeak.org for all the report I did on that
hierarchy).

Stéphane and I are working hard to improve the current hierarchy and
make Nile something worth to use.
