Yes, I would also be extremely interested in the patch.
It would actually be very(!!!) useful to have available variation of 
ecrt_master_receive() that would block and wait till the transaction is 
done and then returns ASAP when it can.
The other option would be some notification from master or NIC that it 
received and so ecrt_master_receive() call is safe now.

Thanks,
Ian
