Ah, this has to do with the fact that a long and unsigned long on x86 Linux
is actually 8 bytes (instead of 4 like on Windows).
We'll take a look at changing the formatting specification to account for
this difference in sizes, and if it can't be done easily before the 2.3
release, then we'll revert the patch in r3090 to re-incorporate
Please still send the output of /proc/<pid>/maps just so we know how it
looks for the future.
