Reserving k = 249 and k = 109 at 2M.

249 is the k<300 with the lowest largest-known-prime, 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 2000-2050 range and unreserve 249 at 2055k in a couple weeks.
