i imagine that kelvin-helmholtz is so long because there's some kind of balance related to radiation pressure (vaguely vaguely like eddington limit?) but i may be way off - never thought about it before. if it is radiative pressure (or anything related to being hot) that holds things up that means that you'll still get an initial collapse and ignition. so i think initial "inner" thermal equilibrium will be much faster, but final steady state could take a long time. and why on earth (or sun) is this chatfilter? delete the stupid answers, not the question. i realise it's not one of your valued "what stupid piece of crap for my kitchen should i waste money on today because i can't cook for shit but boy i know how to use my credit card like a pro?" questions, but it still has a valid answer.
