Question about 4.2 swap space and pstat -s

Alas, it's not a "problem", it's a feature.  4.2 uses a "more
efficient" allocation algorithm for the swap space, which unfortunately
results in fragmentation thereof.  Running large processes like Emaces
seem to result in huge amounts of wasted space.  There is apparently no
"fix" for this.

Perhaps some hardy soul might consider retrofitting the 4.1 swapping
code.  Many sites like yours and mine, who have lots of physical memory
and relatively small swap areas, would appreciate it.
