I have tried compiling webkit with O3 optimisation.  This has given a
significant performance improvement (halving the CPU load) over the O2

There are various suggestions that O3 may genrally introduce unexpected
behaviour due to the way the code is optimised.  Has anyone had any
experience of this with webkit?  Would anyone recommend steering away from
using O3?
