Follow-up to BIND upper limits questions

I'm making some progress trying to tune BIND 8.2.1 to handle a config file
with a large number of zone directives (in the 1 million range). By playing
with NEWZONES I have managed to get a reload of a config file with 500000
zones to happen in just over 3 minutes on a dual CPU Ultra 60 w/ 2 GB of RAM.
In the hopes that I can improve things further I have the following questions:
1) Can BIND be instructed to incrementally load new zones rather than have to
digest the entire config file to pick up a few new zones?
2) Is there any way to get an answer out of BIND while it is reloading? When I
do a nslookup during a reload it hangs until the reload has completed.
3) Why does BIND apparently fork itself when encountering a large config file?
I wind up with two named processes after confronting BIND with a large config
file. And is it possibly to prevent this forking in the hope of improving
performance of the reloads?
