mysql hiding from top

[Zbigniew Szalbot]

hello,

Today I have finally upgraded my system to 7.1-RELEASE and just noticing
that mysql process is not being shown via the top command.

  PID USERNAME  THR PRI NICE   SIZE    RES STATE  C   TIME   WCPU COMMAND
 1612 root        1  20    0  9212K  6716K pause  2   0:26  0.00% perl5.8.9
  966 www         1   8    0  8236K  5452K nanslp 2   0:22  0.00% perl5.8.9
 1594 root        1  20    0  8740K  6220K pause  0   0:12  0.00% perl5.8.9

However, if you grep processes, you can see it should be displayed in the
top entries.
$ ps ax |grep mysql
32880  p0- I      0:00.00 /bin/sh /usr/local/bin/mysqld_safe...
32906  p0- S      1:33.72 /usr/local/libexec/mysqld...

I can live with that but maybe there's some explanation for this?

Thanks!
