Now I am worried about this, though I have voted for keeping the
counter.
NEC Cenju has a non-MPI library including PUT/GET functions whose
implementation relying on interrupt handling. With that in my mind, I
have taken the role of MPI PUT/GET to provide a rich functionality
with a moderate performance.
If the intention is to provide the best possible performance on any
particular platform, then the counter feature does not look right.
I imagine people trying to introduce Window_expose/deliver must have
had the latter intention, as cache-coherence could be handled by
interrupt handlers, without using exporse/deliver.
