Thanks for adding this man page.

The description for PGET_NOTWEXIT is incomplete. It not only rejects
processes with P_WEXIT set, but also zombies. In other words, if
PGET_NOTWEXIT is not set, zombies are acceptable.

This is really wrong since e.g. procstat -k should work on processes
with P_WEXIT set but not on zombies, but it should probably be
documented the way it is.
