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
