I'll stop test sieving for a while if we don't get selected for the BOINC Pentathlon. Do we have enough work queued if we do get selected?

There's not much difference between degree 5 and degree 6, but degree 5 sieves better at higher special-Q so will probably have slightly fewer duplicates.

Sieve on the rational side with 14e from 20M to 160M.
