> DIGY and Doug discussed this issue during the 2.9 port, and this is a patch to give 2.9
the expected behavior of actually ensuring the OS flushes it's buffers to disk.  DIGY suggested
using the kernel32 method FlushFileBuffers, and after investigation he was correct!  FileStream.Flush
doesn't do that - the OS could still be caching it.
