Please, this issue has been confirmed as bug? Or is it a miss use of the 
library? 
Our whole appication depends on this.

I've replicated this just using extjs.  I'm trying to find out what objects are 
not 
claimed by the GC but at first look it seems that there are quite a few of them.

A few pointers here:
- Doug is using a different paradigm to workaround this issue.
http://gwt-ext.com/forum/viewtopic.php?f=5&t=3206&p=10478
- A patch was issued here to address some memory issues by a extjs user:
http://extjs.com/forum/showthread.php?t=45782
  I tried the patch and it does reduce the memory footprint on creating 
windows/panels.  However it still have some more left.

I got (also) a big memory leak problem in our app... with GWT 1.5.3 + GWT-EXT 
lastest
(+extjs 2.0.2)

As the guig's patch is based on extjs 2.2, I think we can't use it with gwt-ext
because of the f***ing famous licence change...

don't you think the same ?

And the Doug way of coding GWT app seems to be a good way to solve the problem 
but i
can't apply this to my app ! It is a good tips but not an acceptable solution
(nagivation dispatching with the entrypoint...).

What is the solution to get the memory back when opening and closing tabs ????

My boss is going to ask us to remove all the tabs from the application if we 
can't
find any valid solution.... please help !
