* put rdma operations in the send event queue instead of receive because it's

Просмотр исходного кода 
easier to do event accounting that way
* greatly increase receive event and buffer sizes.  We're still about half
  of what Cray defaults to, so I don't feel bad about the increases
* Implement a pre-pinning optimization for eager fragments - will be
  pinned on first use and left pinned for the life of the fragment
* Since we can't have two receive frag callbacks fired at the same time,
  don't have receive free list - just keep one receive fragment in the
  module.  Saves a big free list and all that interaction.
