No, I don't think you can get the performance benefits without
violating this particular rule. At the time, we looked at all of the
implementations we had and all of our editors would not be affected by
relaxing this constraint.

The core issue is that we parallelize what files we checkout/update
across a number of connections. In order to adhere to this particular
constraint, we can't parallelize outside of a single directory at any
given time as this editor rule requires that only one directory (and
all children files) be open at a time.

If you see a way to efficiently parallelize checkouts across multiple
directories *and* adhere to this constraint, I'm all ears. But, when
we discussed this way back yonder (don't recall if it was on IRC or
email at the time), there didn't seem to be any way around it and most
felt that the constraint could/should be relaxed. -- justin
