I didn't request (or push) for any change in the first place because i
do not know what that change does in the first place. I simply tried
to benchmark it to see whether such a problem occurs. This testing was
done with 1.99~rc1 release (not bzr trunk and not with the 16 KiB
alignment patch) and I am not sure whether the same results might
occur bzr trunk. I do not know whether the proposed change will solve
the problem because i am not a programmer. Of course i will test any
patch you send to me if i have time and if i am able to obtain any
useful info.

The only info you (phcoder) mentioned is that you tried for dynamic
cache allocation
(http://www.mail-archive.com/address@hidden/msg15793.html). If you
can provide an updated patch i will test it (is the blockio patch same
as this?). Sorry but i don't mean to offend anyone in this mail.
