Well good.  It seems we all agree there is a problem and on the
general solution.  I haven't thought about Brett's idea to see if it
could work or not.  It would be great if we had someone start working
to improve the situation.  It could well be that we live with the
current code for 2.5, but it would be great to use arenas for 2.6 at

Niko, Marek, how would you like to lose your lurker status? ;-)
