2.6.16 leaks like hell. While testing, I found massive leakage
(reproduced in openvz) in:

*filp
*size-4096

And 1 object leaks in
*size-32
*size-64
*size-128

It is the fix for the first one.  filp leaks in the bowels of namei.c.

Seems, size-4096 is file table leaking in expand_fdtables.

I have no idea what are the rest and why they show only accompanying
another leaks.  Some debugging structs?
