Re: [HACKERS] Re: [PORTS] pgmonitor and Solaris

FYI, the WU-FTPD code (2.6.0 or better) has a couple of more platforms
including UnixWare.  The UnixWare code will need /dev/kmem permission to
change it's stuff, so I don't know whether we want to do this or not, but
if people are looking at the ps stuff, please look at this as well.
