Was that one lost? > Dropped? Lives elsewhere? 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
