Agree on the retry solution. Yes, two important factors are: intervals,
times. I suspect if it is a dedicated server, serveral retry can handle it.
But for a server might running backup together, who knows how long we need.
But in either way, I don't think an endless loop is needed -- at most 3
minutes (since s_lock() does this :-)).

Also, this is a partial solution to the "invalid parameter" win32 IO
problem. There are some other cases like ACESS_VIOLATION error need more
evidence to pin down.
