Hohum. You are running in WINDOZE mode, right? Otherwise cwsdpmi might
create a swap file which could explain the difference as your program
is probably bigger than the little statfs test program.

One thing to try is to add printouts in every while and if statements
in statfs() to see which path the code is taking and see if there's a
difference.


Right,
