fastthread 0.5.3

I’ve just released fastthread 0.5.3, which is mostly a bugfix release—SizedQueue has been horribly broken in many of the prior releases, but I think this one finally puts the bugs to bed.

I’m going to let people use this one in production for a while, and then assuming that everything works out okay, we’ll proceed to 1.0 and then a patch for inclusion in Ruby stdlib.
