I don't know what alternatives you consider better - IMHO the in kernel
version is way smaller, minimal slightly more efficient, and a lot more
elegant than any vfork based hack I could think of. Besides, I wouldn't
know how to do all the dirty libpthread changes to make that thread

I see the first point (but it is ok in this usage, maybe needs a few warning
comments here and there). I'm not confinced it falls into the same categories
as the other points ;-)
Anyway, I will check if we can avoid it - this would make the overall
change far less intrusive, which is always a plus.
