Well, it was fixed (thanks!) back then in June 2001.
However, the misbehaviour has returned - I can't say exactly when,
but with 2.4.18 it happenes again and just caused my computer to
hang for quite a long time (dumping 10 cores of empty 512 MB per process
takes some time... :-| )
Can you fix it again (and set up a booby-trap in the source that immediately
electro-shocks anyone trying to revert to the old bad habit)? :-)
