hm, Thomas pointed it out that this wont solve all the problems as
quicklists have a built-in "preserve me" throttle (which is rather
stupid).

the right solution is to get rid of quicklists altogether (Thomas
expects to have patches for that later today).

If anyone implements a _sane_ general purpose allocator that can
preserve constructed objects then i'm all for utilizing it in x86 too,
but quicklists arent that mechanism ...
