I once suggested this patch:
--- sys/vm/swap_pager.c Mon Dec 28 00:21:12 1998
+++ sys/vm/swap_pager.c Mon Dec 28 00:21:52 1998

@@ -1144,4 +1145,5 @@ swap_pager_getpages(object, m, count, re

}

} else {
I remember 1 positive response on it, and 0 negative responses. Feel
free to try this patch.
As a side note, IMO the code (that the patch ifdef out) is not a very
good idea, whether it is related to the "daemon dying" bug or not. There
is usually some amount of allocated but unused swap space (20-50%, I
think), and this space apparently left allocated but unused forever,
and the code free used swap space instead....
