Do you have any plans to get pgdelete() out from under Giant? That
would allow leavepgrp(), doenterpgrp(), enterpgrp(), enterthispgrp(),
setsid() (mostly) to be taken out from under Giant, and perhaps a few
others.
I was thinking of simply having a free list of sessions and process
groups, locked by PGRPSESS_XLOCK(). pgdelete() would then not have
to call FREE() and setsid() would almost always be able to pull a new
structure of the appropriate free list and thus not have to obtain Giant
for the MALLOC.
