That's an option too. I'm currently trying to get top to display
something like this (80 columns are used for text, so use a slightly
wider terminal to view this properly:

This includes at least the following changes (some not visible):
+ The entire header line is limited to the window width too.
+ The USERNAME column is hard-limited to 8 characters.
+ The THR column is displayed as /1 after the COMMAND, like the
prstat(1M) command of recent Solaris versions.
+ The CPU/WCPU columns occupy the same space and can be toggled with
the 'C' keyboard command.
+ When UID numbers are displayed, hitting 'u' will read a UID instead
of a username.
+ When the view is toggled between processes/threads, the NTHR part
becomes the thread ID of the particular thread.
Hopefully, I'll have these changes running on CURRENT before the weekend.
If no strong objections are voiced for any of these changes, I'll test
it on CURRENT for a while, then ask for approval of a commit to HEAD and
merge it to 5-STABLE after it's been tested enough on CURRENT.
