swap questions

When I perform a 'swapon -s', what exactly is "Reserved space"?

I have a machine with the following swap status:

[ericksco]minga:/var/adm$ swapon -s
swap space below 10 percent free
Swap partition /dev/rz0b (default swap):
    Allocated space: 62807 pages (490MB)
    In-use space: 20350 pages ( 32%)
    Free space: 42457 pages ( 67%)


Total swap allocation:
    Allocated space: 62807 pages (490MB)
    Reserved space: 59129 pages ( 94%)
    In-use space: 20350 pages ( 32%)
    Available space: 3678 pages ( 5%)

I would like to find out what falls under the category of "reserved" so I
may trim down swap usage a little.

Thanks,

Cory
