`--reindex' involves chomping down lots of mail, so it benefits
from parallelization just like the initial indexing.  It's
also a bit surprising to specify `--jobs/-j' without parallel
processes, so ensure we turn on parallelization there, too.

We can simplify initialization here, as well, since neither
`eval' nor `V2Writable->new' should be in this code.
