I believe the scenario can be like this:
You are on page A.
You click on ajax link on page A.
Before the request is completed, you go to page B (non ajax link). This
is little tricky, because during ajax request the session is locked, but
I guess it can happen (the ajax request is still connecting, for example).
So now you are on page B. Then the ajax request from page A is being
processed. The page B is removed from pagemap. But you are still on page B.

So what request comes first?
The ajax request should always do -1 (so latest release)
So if the request from the new page did come first then the ajax request
shouild work on that new page.
If the ajax request did come a bit earlier then there shouldn't be a
problem at all because
the last reqest will be the normal link click for a new page.

I cannot figure out any workaround myself.
UnversionedBehaviorListener seems to use -1 as
page version number, would it make any sense to try to alter PageMap
so that
if version is -1 the page stack is not cleared ?
