Random lunchtime observation:

A lot of the calls to vsprintf are from 
TypeStruct::toDecoBuffer/TypeClass::toDecoBuffer/TypeEnum::toDecoBuffer

which all do

            OutBuffer->printf("%s", name);

Is that needed, or would changing them to

            OutBuffer->writestring(name);

be more efficient?
(it seems like it might, albeit only very slightly).
