we've talked about this off-and-on for quite some time, providing a
mechanism for sending an unexpected message that sets the server up
to receive a large incoming request. is it time to implement this?
What about putting the looping in the state machine for IO? From the
server's perspective, it looks like multiple IO operations, but from
the client its just adjusting the next state action after the IO
completes. This only fixes the problem at hand, but its a lot easier
to implement.
We might also try to reduce the size of each segment's encoding. If
the type is indexed, the optimal encoding size should be 16 bytes (5x
smaller).

additional messages mean a single call to PVFS_sys_io
