I have the process that first runs in 3 threads but later two active

Process time goes down: 0:34 -> 0:03. Also WCPU goes down 90.92% ->
1.17% even though this process is CPU bound and does intense things
right after threads exit.
getrusage(2) though, called in the process, shows the correct user time.
I think this is the major bug in the process time accounting.
could you check, whether kern/128177 or kern/140892 describe your situation?
I have ULE scheduler. kern/128177 talks about single thread with ULE
scheduler, and my issue is with threads. So I am not sure if it is
related. There have been no motion on kern/128177 since Feb 9, 2009.
kern/140892 is probably the same as mine.
In any case, both these PRs have to be fixed since they are very user
visible, not just some obscure issues.
