  Would there be any objection to the following patch, it makes it easier
  to see in top(1) which thing a process is waiting for.

The rule is that wchan messages should be at most 8 characters (see,
e.g., condvar(9)).  These wchan messages satisfy that, as far as I can
tell.  Maybe top(1) should be adjusted to show all 8 characters
instead?

It is 6 now because of /<n>...

Hmmm. I still have a 24-core machine (dual AMD 12-core processors) sitting in my too-expensive-to-run-and-cool pile. If I were to fire this beast up, would top(1) be limited to displaying only 5 chars of waitchan?

:)

(PS I'm really not interested in bring this machine up - I've already cannabilized it for several parts, so it's probably no longer bootable.)
