Eeek, no that is supposed to only be used debugging. The *last* thing you want
is to have resources of *any* crashed application laying around. Also, you
can't keep the data as Pixmaps then. Also, I think those resources will stay
around unless if you use temporary.

Perhaps one could catch all the close signals, spawn another instance first,
then manually copy the pixmaps over before actually exiting. Sloppy tho ;-)
