10.2 used those options with these values:

  dynamic_pager -H 40000000 -L 160000000 -S 80000000 -F ${swapdir}/swapfile

They were removed in 10.3.

Thanks for testing that.

Quitting processes or logging out can trigger dynamic_pager to remove one
or more swapfiles.  I do that more often than rebooting since it won't
take long before two or three are recreated on my 640MB iBook anyway.  I
usually have four total, then play the process-quitting game if swapfile4
(and more) persists awhile.
