I'm pleased to report that with the 2.6 kernel that is no longer the case
(http://lkml.org/lkml/2005/6/29/11). Swap partitions and files have the same
reliability and performance _unless_ the swapfile is badly fragmented. We've
had great success adding swapfiles to systems that have grown memory tight in
thier old age. It beats the crap out of taking an outage to re-partition.

OTOH, I just repartitioned my laptop to extend the swap partition because I
added memory and could no longer hibernate because swap was to small to hold it
all. At today's drive prices and power costs, it's worth having a large enough
swap partition for anything that can hibernate and wake faster than it can
boot.
