Reserving k = 249 and k = 109 at 2M.
249 is the k<300 with the lowest largestknownprime, at 251036. I will test this k just until I find a prime, or lose interest.

Well, that was fast. 249 has a prime at 2001627. I stopped the second core at 2055k, so I'll let the first core finish its 20002050 range and unreserve 249 at 2055k in a couple weeks.

k=281 complete to n=2M, one prime found (281*2^18608621), releasing this k.
Taking k=293 from n=1850k to n=2M.
