I do set the order tag during allocation/prepare, but the defined
semantics are that the tag is only valid after send/put/get. We can
set them up any where we wish in the BTL, the PML however cannot rely
on anything until after the send/put/get call. So really this is an
issue of semantics versus implementation. The implementation I
believe does conform to the semantics as the upper layer (PML)
doesn't use the tag value until after a call to send/put/get.
I will look over the patch however, might make more sense to delay
setting the value until the actual send/put/get call.
