(I guess, but I'm quite sure)
In special cases, they are performance sensitive.
TNG uses a lot of rpc calls for everything and everytime I
log into an ntbox, that is a part of my samba-domain I get
told about a "slow network" connection, I currently address
this to the box (p100) but also to the bunch of rpc calls
that happen to authenticate even normal share accesses.

Note, that this is a special case and does not affect HEAD
immediately, because TNG uses quite another model for auth
and there are only a few optimizations in place.

[...other stuff and suggestion for new lpq-system...]

The suggested lpq technique sounds quite okay to me. It
makes sure, that the response-times are good and also has
non-samba-jobs in the queue.

The child just should make sure, that the database isn't in
a broken state, so that clients get some useless info. On
the other hand, it shouldn't lock the db all the time (we
wouldn't win anything.)
