Hello Felix, yes, I'm aware of suspension and the magic going on inside that egg is precisely what I referred to by "fiddling around with green threads". In fact, protobuf can easily act as a drop-in replacement for s11n and I just verified that it does work just fine with suspensions! So I can say with more confidence now that continuation serialization through protobuf is functional. Apply the attached patch to the the suspension egg, install it and see for yourself :-) Ciao, Thomas -- When C++ is your hammer, every problem looks like your thumb.
