 reasonable before we make any actual changes.

 +1, and, I actually suspect the overhead in the parser is marginal
 compared to the SQLite3 related load.

 Also, using multiple threads will require some trickier
 consideration/design work.  b10-loadzone is a simple wrapper for the
 datasrc `ZoneLoader` class; it doesn't directly access
 `MasterLoader`.  To make it possible for b10-loadzone, we'll need to
 make some substantial extensions to underlying libraries, and probably
 also to b10-loadzone itself.

 So, right now, I don't think this task is estimatable.
