The interface exported by the RPC library allows users to simply send
and recieve fixed sized packets without worrying about the data motion
underneath. However, this was broken in the current implementation. We
can think of the send and recieve implementations in terms of waiting
for ownership of the buffer, using the buffer, and posting ownership to
the other side. Our implementation of `recv` was incorrect in the
following scenarios.
recv -> send // we still own the buffer and should give away ownership
recv -> close // The other side is not waiting for data, this will
result in multiple openings of the same port
This patch attempts to fix this with an admittedly hacky fix where we
track if the previous implementation was a recv and post conditionally.
