Hello.  As part of some work I'm doing during my day job, I have a 
reason to try to create files larger than 2GB on a NetBSD 1.4.x system.
The following program failes with a  ENOSPC error when trying to create
such a file when the file in question  is still 1.5GB in size and the
filesystem is only 70% full.  Any idea why this would be happening?
If it's something silly I'm doing, let me know.
-thanks
