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.
