--- Comment #12 from John F. Carr <[email protected]> ---
I got another hang on kldload and this time ^T over the ssh session was
responsive for about a minute, ending with

load: 0.19  cmd: kldload 67182 [running] 53.73r 0.00u 0.01s 100% 1944k

The process is using 100% CPU but none of it is counted towards user or system
time.

As I understand sched_4bsd.c and kern_clock, the percentage is based on what
thread is saved in curthread when the clock ticks and may include time that an
ethical accounting system would not bill to the owner of the thread.  "Note
that we charge interrupts to the current process, regardless of whether they
are ``for'' that process".
