Strange top(1) output on 5.4-RELEASE

[Alexander S. Usov]

Hi!

I have just noticed this strange thing:
% top
last pid: 50566; load averages: 0.28, 0.26, 0.23 up 1+18:25:52 16:48:31
90 processes:  3 running, 87 sleeping
CPU states: 4.3% user, 0.0% nice,  6.2% system, 1.9% interrupt, 87.5% idle
Mem: 315M Active, 39M Inact, 120M Wired, 18M Cache, 60M Buf, 984K Free
Swap: 512M Total, 31M Used, 480M Free, 6% Inuse

  PID USERNAME  PRI NICE   SIZE    RES STATE    TIME   WCPU    CPU COMMAND
48650 root       91   -5 77028K 33408K select   2:34  6.05%  6.05% Xorg
50520 usov       96    0 28268K 17564K select   0:01  0.93%  0.93% kdeinit
..... some output skipped .......
49961 usov       96    0 31600K 18076K RUN      0:08  0.00%  0.00% kdeinit
48740 usov       20  -76 11772K  6560K kserel   0:07  0.00%  0.00% artsd
  464 root       96    0  3080K   844K select   0:06  0.00%  0.00% ntpd

Note the -76 as a NICE value for artsd. In the same time "ps axl" shows NICE
value of 0, which is also quite strange as I have artswrapper installes and
"artsshell status" reports real-time status.
I observe this on 5.4-RELEASE-p3. Top & ps binaries are supposed to be in
sync with the kernel I run (I have already tried rebuilding libkvm & top,
but this changes nothing).

Any ideas?
