It strikes me that we really need to try reconnecting to the shared

Adding a backoff would make the code significantly more complex, with
no gain that I can see. Just loop a few times around the
one-second-sleep-and-retry logic.
I concur with Greg's opinion that the need for a sleep here at all
is pretty fishy, but I doubt anyone really cares enough to find out
exactly what's happening (and it being Windows, there may be no better
solution anyway ...)
We've seen similar things with other Windows file operations, IIRC. What
bothers me is that the problem might be precisely because the 1 second
sleep between the CloseHandle() call and the CreateFileMapping() call
might not be enough due to system load, so repeating the cycle without
increasing the sleep period will just repeat the error.
