Clean up (or if antipodic: down) some of the msgbuf stuff.
Use an inline function rather than a macro for timecounter delta.
Maintain process "on-cpu" time as 64 bits of microseconds to avoid
needless second rollover overhead.
Avoid calling microuptime the second time in mi_switch() if we do
not pass through _idle in cpu_switch()
This should reduce our context-switch overhead a bit, in particular
on pre-P5 and SMP systems.

will have to be fixed.

for users who are root, or in group wheel. This is useful on large timesharing
systems where a PS command can cause the system to grind to a halt. The
ability to get the information isn't diminished for those who really need the
additional detail (administrators.) Normal users won't see any difference unless
the processes are swapped out. The "really get it mode" is invoked by the
use of an additional flag in the command string "-f". New/old behavior is
selectable with a compile option.

VM structure (eg: credentials etc) and it's highly unlikely we'll ever
get to see the "tainted" BSD<=4.3 VM code in public use. Although it
indicated the way some things used to be done, it obfuscates things too
much.

into 2.2, for the day when we bump up the username length there too).

This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.
Boy, I'm glad we're not using sup anymore. This update would have been
insane otherwise.
the full argument vector.
I've bumped into a few things that expected this switch to be present,
the most recent was the snmp package in ports. I'm not 100% sure of the
origins of this, but Linux has it, so does the "BSD-compatable" version
of ps on our SVR4 systems (so I assume SunOS has it too).

list the processes belonging to a particular user without having to use
`-u' and grepping for the username. Basically you can now get a short
`ps -x' like list (with more space for the command) for other users.
allow more than two tty characters.
David Greenman pointed out that when a process that had been revoked from
it's controlling tty, the "-" sign was detached from any two-character
names.
This gives us more room to breath with tty names, especially with drivers
that support large numbers of ports.. eg: specialix and digiboard.
This does not actually change the current tty names, it just allows room
for reporting more characters if the drivers use them.
