The solution is a modified event architecture and jettisoning relinquishProcessorForMilliseconds:.  Search the archives (squeak-dev & vm-dev) for “event driven vm”.  This is work that should have been done a long time ago (I did this for the VisualWorks vm back at the turn of the century or thereabouts).  But it isn’t going to get done unless someone steps up.  My input queue is full to overflowing.
