Here is another way to write the code without having to pay the
expensive initialization of sendreq.
first_time = 0;
for ( btl = ... ) {
if ( SUCCESS == sendi() ) return SUCCESS;
if( 0 == first_time++) set_up_expensive_send_request();
if ( SUCCESS == send() ) return

Currently, the PML chooses the BTL first. Once the BTL choice is

However, in the case sendi cannot do the job we expect, the fact that
