[xemacs-hg @ 2006-02-27 16:29:00 by crestani] - Introduce a fancy asynchronous finalization strategy on C level. - Merge the code conditioned on MC_ALLOC into the code conditioned on NEW_GC. - Remove the possibility to free objects manually outside garbage collections when the new collector is enabled.
