I nearly forgot the most important: thanks to Jan, we do have a built-in
performance profiler in recent Adeos releases for x86, providing precise
timing information about a running kernel, which can be used to locate
high latency spots for instance.
The patches in the following directory should be applied incrementally
against an Adeos-patched kernel:

A ppc version is in preparation.
