2.6.0-test5/6 (and probably 7 too) size-4096 memory leak

Hi there!
I want to report a memory leak for 2.6.0-test5 that I've noticed today on
a mail server after 32 days of uptime.
As I'm upgrading it tomorrow to test7 I wasn't going to report this until
verifying if the behaviour continued, but I saw on kernelnewbies that
others were having this issue with test7 too, so I decided to post a
report with the information before I reboot the server.
The attached files are gzipped for space reasons, and were taken at night
when the server isn't very loaded.
The workload is a simple sendmail with ipop3d and imapd, nothing much, for
about 6500 users; the machine is a dual Pentium III with 1gb of RAM and a
couple of SCSI disks.
Slabinfo reports that size-4096 has 104341 active objects and growing.
On another box at home I see the same issue with test6, but "only" with
11612 objects; I'm not posting info on this box as I guess the mailserver
is much more important because the leak is really noticeable.
Please let me know if I can help with anything.
Thanks,
Alberto
