[Twisted-web] Nevow.Athena.PageWidget - events not caught in IE

Just a thought:

We ran into problems with Athena and the releases from nevow after
SVN 13786 (was a major upgrade) and IE due to the following policy MS 
introduced: IE seems to limit the connections allowed to 2max, which 
blocks IE when for instance running the Athena calculator sample and 
doing a page refresh or two.

It seems that tearing down athena and bringing it up again may in some 
cases 'hang' IE (socket states is TIME_WAIT) for around 120 secs. The 
same happens when going from one livepage to another.

I am writing this on a hunch and from memory, apologies if the problems 
are not related.

If they are, I am glad to help digging :-)

Our solution for this particular problem was to hang back on SVN rev 
13786 for nevow until fixed. Server runs ok with several hundred 
LivePages connected.

HTH, Werner
