Voltaire has the Linux (and core) OpenSM maintainer. What does he say
about this ?

Problems like this were seen with older OpenSMs which is what the
Windows version is. IMHO OpenSM in Windows needs to be updated to the
latest and greatest. Until that occurs and it seems no one has the
cycles for this, I think we have and will continue to chase our tails
on many such issues. Any chance Voltaire has an interest in doing this
since you have customers who appear to be relying on this ? It would
do the community a large service.
