:"pstat -s" on SunOS4, and "swap -s" on SunOS5. From Solaris man page:
:
::    -s             Print summary information  about  total  swap
::                   space usage and availability:
::

::                                  (in      1024-byte     blocks)
::                                  currently allocated for use as

    Yah, that's what I thought.  A solaris expert could tell us
    for sure but I am pretty sure those are simply cached swap
    blocks after-the-fact, not actual reservations on potentially
    swappable space.
