>Description:
stat64 system call in linux32 emulation does not work on files on tmpfs.

Or, that is, the system call itself does work, but when glibc tries
to convert the stat64 struct to normal 32 bit stat, it fails because the
files on tmpfs have huge inode numbers.
>How-To-Repeat:
Try to run linux32 binary that uses ORBit2, and observe endless stream
of:

Can not stat /tmp/orbit-arto
>Fix:
Smaller inode numbers for files on tmpfs?
