Hi Florian,

you are a hero. In a very artificial benchmark which just consists
of threads and exception handlers, a 32 bit Linux executable now
is *twice as fast*!

In a real-life scenario we are "only" seeing an improvement of about
10%. But really, this is huge progress. I think everyone will
benefit from these improvements.

We have not yet tested this on ARM (does it work on ARM?).

Bero will do more testing in the next couple of days and report
