In my opinion, debian unstable is now "stable". Probably, this is
because it has been
pretty much frozen except for bug fixes for several months. It taken
many months but
the SMP stability problems are pretty much fixed. Helge's machine was
running stably
at a load average of ~250 in hackbench testing. It used to crash reliably.

It is great that gentoo supported users through a rocky period.

Debian 2.13-38. Nothing much has changed since your patches were
integrated.
Kernel was 3.9-r7+.

That would be great.
