Discussions are good.  We understand the problem better.  Now I still
think we don't understand every aspect completely, so continuing the
discussion makes sense.

This thread started out from a bug, that seemed to be caused by the
freezer (we still don't exactly know what it was caused by), and the
discussion uncovered various problems _with_ the freezer, that up to
now no other _proper_ solutions have been propsed than to remove the
freezer.

Yes, we can live with hacks, but we don't want to live with them
forever.  Even if they seem to be simpler than a big rewrite, the long
term headaches are not worth it.
