On a slightly related note.  I've noticed that QuickFIX can be a
little over-aggressive in terms of issuing ResendRequest messages and
I think it might make sense to implement some level of throttling on
these.

For example, if a counterparty has a large-ish number of messages in
flight when a gap is detected, each will cause QF to issue a
ResendRequest for the same range of missed messages.  The remote side
will honor all of these, resulting in several times the necessary
message traffic to fill the gap.

It might make sense to keep track of the range and time of the most
recent ResendRequest in the SessionState and not send a new
ResendRequest if the outstanding one would satisfy the same range of
messages and no more than <X> seconds has elapsed.
