Hi Keith,

In ResourceHashtable, how did you settle on size 1019? I see it's a prime
so presumably you're worried about collisions? I'd think a power of 2 would
give you some speed up as you can avoid the relatively expensive mod
operation, but just curious what your thinking is here.

Nice job on the "short" :) writeup by the way.
