this implementation seemes flawed to me.
closesgrp() appears only to free the memory of the Srv*
nodes, but doesnt actually free srv->chan, srv->owner
and srv->name.
also the locking seems suspicious. as the global Srv*
list was just replaced with per process one, but we'r
still only have a single srvlock to serialize
concurrent access to it.
so far, the srvgrp can only be reset or shared depending
of the RFCSRVG flag. once you implement copying you'd
need a lock per Sgrp. i'd prefer to have a lock per
Sgrp right now and remove the global srvlock.
pexit() should move the sgrp = up->sgrp; up->sgrp = nil
in the exiting qlock(&up->debug);... block instead of
making its own.
why do we need /zrv? is there a new devzrv.c device that
was missing in the diff?
