On several FreeBSD machines I have the following problem:
What FreeBSD version? (It matters)
7.1-PRERELEASE FreeBSD
But I can experience it also on a 7.0 machine. Seems that top reports
incorrectly processes with multiple threads.

However mysqld time is actually

1079 con- S 70:03.64 [mysqld]
^^^^^^^^^^^
------------------------------------------------------------------------------------------------------------
99156 p0 S+ 0:00.00 grep mysql
Anyone who can explain this?
