label is choosen as last printout (ucomm suffers of this such bug
too). That bug is caused by the fact that the fixed size of
printout doesn't leave enough space for them to be printed out.
Implement ucomm and comm commands with a dynamic size lenght for
buffers.
[2] On AMD64 architecture pointers don't have enough chars space to
be shown (8 chars while they need 16). Fix them by providing
a variadic space so that it fits well on both 64 and 32 bits
architectures.
[3] Check a return value of malloc() that wasn't checked before.

kthread_add() takes the same parameters as the old kthread_create()
plus a pointer to a process structure, and adds a kernel thread
to that process.
kproc_kthread_add() takes the parameters for kthread_add,
plus a process name and a pointer to a pointer to a process instead of just
a pointer, and if the proc * is NULL, it creates the process to the
specifications required, before adding the thread to it.
All other old kthread_xxx() calls return, but act on (struct thread *)
instead of (struct proc *). One reason to change the name is so that
any old kernel modules that are lying around and expect kthread_create()
to make a process will not just accidentally link.
fix top to show kernel threads by their thread name in -SH mode
add a tdnam formatting option to ps to show thread names.
make all idle threads actual kthreads and put them into their own idled process.
make all interrupt threads kthreads and put them in an interd process
(mainly for aesthetic and accounting reasons)
rename proc 0 to be 'kernel' and it's swapper thread is now 'swapper'
man page fixes to follow.
- p_sflag was mostly protected by PROC_LOCK rather than the PROC_SLOCK or
previously the sched_lock. These bugs have existed for some time.
- Allow swapout to try each thread in a process individually and then
swapin the whole process if any of these fail. This allows us to move
most scheduler related swap flags into td_flags.
- Keep ki_sflag for backwards compat but change all in source tools to
use the new and more correct location of P_INMEM.

the header title string "bar" extends to the end of the argument
even if it contains commas or spaces, unlike in RELENG_4 or earlier.
The modern syntax agrees with SUSv3.

all column-headers to print in lowercase by default. I was in too
much of a rush in committing 1.75, and didn't notice that the case
had changed. This time I did considerably more testing, and used
'diff' instead of just quickly eyeballing the results...
Apologies. I expect this means the dunce cap is mine for awhile.
If this doesn't work, I'll just drop back to 1.72 and hide under
my desk for awhile.

E.g.: stat (for state) or pcpu (for %cpu)..

- Document the fact that empty heading text suppresses the
heading line (e.g. 'ps -o pid='), as this is very useful
in scripts.
- Describe logname keyword more completely.
- Describe the printing of arguments more completely.
- Put lockname in the correct alphabetical order in the list
of all keywords.
- Correct sentence in standards section.

to exceed 10 megabytes in size (especially in X), bump the max
column width from 4 bytes to 5. This will make the ps auxw output
uniform again when a process's rss exceeds 10 megs.
It should be noted that when 5 digits becomes to small, other
solutions should be explored such as displaying them in megabytes
or having ps automatically re-size column widths.
