Re: fsync and semctl errors with 8.1.5/win32

I forgot to mention - this problem is occurring on multiple Windows
machines.  One of them is running Windows XP Professional.  The other is
running Windows Server 2003.  I have disabled indexing, virus scanning,
and all non-essential services on both of them.  The problem continues
to show up even when no queries are being run (although it might always
start while queries are running)
