http://dovecot.org/test/ This release is built with autoconf 2.59 and libtool 1.9. We'll see how it works out :) The required changes were done by Matthias Andree. - The last fix for connection hanging made IDLE use 100% CPU - We don't use Maildir/.INBOX/ directory anymore, indexes are stored in Maildir-root - Don't crash with FETCH BODY[n.MIME] - Changed %p (protocol)

We have a Linux file server for a set of computer science and engineering labs where each lab contains machines running Mac OS X, Ubuntu Linux, or some incarnation of Windows. At times the these machines become almost unusable and I think I have narrowed the problem to smbd processes soaking up all the CPU on the server. Running 'top' on the server reveals a dozen or so entries like

This patch series introduces the VHD library. It is based on the blktap2 one, with changes coming from the blktap2.5 one. Signed-off-by: Thanos Makatos <thanos.makatos@citrix.com>

I have updated the klibc patchset based on feedback received. In particular, the patchset has been reorganized so as not to break git-bisect. Additionally, this updates the patch base to 2.6.17-git12 (d38b69689c349f35502b92e20dafb30c62d49d63) and klibc 1.4.8; the main difference on the klibc side is removal of obsolete code.
