Yeah I integrated that as well already. I think I'll post the patches
at the end of the Day (French Timezone so in 5 or 6 hours at least) to
be sure nobody has any good remarks to do first. If you want I can share
my branch somewhere if you want to look at it, just ask.

Sorry if I chose wrong words to say that, it is clearly a big plus ! I
wrote it having in mind that very often abstractions and high level APIs
often degrade performance. It does not, and that's a huge win. The point
is that "despite the somehow higher level API we don't loose an inch of
performance".
