The first 7 patches come from my sva/api branch, where I had forgotten
to add the "handle page response timeout" patch. I added it back,
probably after Eric sent this version. But I don't think the patch is
ready for upstream, as we still haven't decided how to proceed with
timeouts. Patches 6 and 7 are for debugging, I don't know if they should
go upstream.

Thanks,
Jean
