the line of people who have asked for this would stretch out the door and
into the street. bind runs from memory rather than from disk, because it
has to be able to answer at wire speed for large values of "wire". we're
working on a hierarchical storage system, basically a memory cache with
LRU, backed by a database. we're also working on a way to load from sql
databases into memory rather than always having to load from disk. it's
likely that the second of those two projects will be complete a year or
so before the first :-).
in 8.1.2++, though, the goal is to be able to check and/or reload a zone
without having to stat() all the others. for someone with 50K zones on
board, this should be a huge speedup.
