Sounds about right to me. Thread-safe PHP needs this and in a few months
this will effect most PHP users who move to Apache 2.0.

Didn't look at it right now, but just from my memory there is quite a bit
of duplication in some of this code and it could definitely be improved.
But we need to be very careful not to break anything.

The right place for such wrappers would be main/. Maybe you should layout
the wrappers before you start implementing them and mention what you would
touch in the code before you start working? This would allow us to give you
some feedback.
