Seems sensible but I doubt it'll make much difference.  It could improve
performance if the system is using a large number of PCBs.  Have you seen
a noticable drop off in performance as the number of PCBs increases?

Yes, we should try and make sure that this is kept to a minimum.  CVS
should avoid the need to keep old code around in the current source.
