Which kernel precisely?  What does "vmstat 1" look like?  If you
swapoff/swapon between application runs does the effect persist?  What
does the application do?  What does /proc/sys/fs/inode-nr contain?

This does not sound like a result of the swap caching behaviour.  Once
you start swapping that memory _is_ returned (or something is not
working as it should).
