I doubt there's an mmap(2) on Windows.  I'd rather call an existing file copy function than make and test my own.

Thanks.  I thought it would be in there somewhere.

We already use boost::filesystem in a dozen places.  It's not a new added dependency.  It gives us a lot of portable stuff that we would otherwise have to have a #ifdef for each OS and test everywhere.
