need several requests at the same time. So maybe pooling of
XmlHttpRequest(s) could work...
Btw, does dojo use pooling (since there was no leak with it) ?
Maybe it would make sense to check how they are getting around
this.

Hi,
There is a browser-side memory leak in wicket ajax stuff when used
with internet explorer. We discovered it when changing our application
from wichet+dojo to wicket+wicket-ajax.
Memory leak occurs only if wicket-ajax is used in IE. With dojo,
there is on leak. Also, in firefox, neither solution leaks.
There is a simple example available at
http://download.syncrontech.com/public/wicketajaxleak.zip
It just displays a number, increments it and displays it again
using ajax.
There is also a memory usage graph which has data from
dojo and wicket-default ajax cases, from that it is easy
to see how differenty these implementations behave.

These runs were done agains wicket 1.2-beta3.
This is a rather nasty problem for us, since we have a lot
of pages, which update themselves very frequently based on
data coming from automation systems.
We did some looking around in wicket-ajax.js but didn't
find anything obvious.
