Those are threaded processes using libkse via libmap.conf, which are
using CPU but do not have any CPU% listed. Scheduler is 4BSD, kernel
was built yesterday.
Any progress on fixing this?
Following patch should give you a number to display.
Since a kse can move from a thread to another, you will
see all threads using same kse have same pctcpu number.
