fcntly.ioctl takes an int as the second argument. If
the value passed is a large 32 bit quantity (0x80046601
for example - EXT2_IOC_GETFLAGS) then I get:

Traceback (most recent call last):
  File "CommSecure-CVS/Operations/checkSpace.py", line
73, in ?
    main(sys.argv[1:])
  File "CommSecure-CVS/Operations/checkSpace.py", line
25, in main
    os.path.walk(file, doDirectory, total)
  File "/usr/lib64/python2.3/posixpath.py", line 282,

    func(arg, top, names)

61, in doDirectory
    flags = fcntl.ioctl(fd, EXT3_IOC_GETFLAGS, "    ")
OverflowError: signed integer is greater than maximum

My _guess_ here is that the code is checking against 32
bit quantities rather than 64 bit when converting to
the C data type?
