Detailed Description

An entry in the operation queue.

Entry identifying transmission in one of our struct Queue which still awaits an ACK.

This is used to ensure we do not overwhelm a communicator and limit the number of messages outstanding per communicator (say in case communicator is CPU bound) and per queue (in case bandwidth allocation exceeds what the communicator can actually provide towards a particular peer/target).
