yowsers. 

as occasionally happens, i mistyped a command and not knowing what 'sa'
was for, read the man page.

on this particular host, i do run process accounting so i was hoping for
something legible.  lastcomm is nice and all, but sa sounds really nice.

at any rate, i started getting stuff like this dumped when i tried to run
it:

openbsd 2.3, alpha.  is a dmesg needed?  here it is, just in case:
(that panic was 39 days ago, had a website that was just eating the poor
UDB alive...)
