Yes, it's happening now. My mail server is running a UP kernel built from
941f5de0 (around Oct. 10), but I can't find a relavant fix on
DragonFly_RELEASE_2_0 branch. I have another box running -DEVELOPMENT,
but its uptime is probably not long enough to reproduce it.

I played with kgdb a bit and found that these 3 processes are on zombproc
but with p_stat==SACTIVE and p_lock==1. I have no idea how it happened.
