Dear NetBSD/i386:

This morning I ran top on a PC which is running NetBSD/i386 1.5 and found a
telnet process was using about 50% of the CPU.  There seemed to be no
telnet session corresponding to it, so I killed the process.  Doing so
didn't seem to cause any problems.  I've appended top's output before and
after killing the process to this message.

I assume the process was left over from when the Macintosh I was running a
telnet session on crashed, but why would it have been using up so much of
the CPU time; and why was that command named telnet instead of telnetd like
the two near the bottom of the list?
