Subject: Moved it all back; the preemptive multitaksing during an event
 handler kills us on all platforms. Going to have to restrict ALL GUI accss to
 happening from one t hread, so going to need to drop uitask entirely and have
 just a start() callback for startup code and a post() function for posting
 requests to windows (like channel sends but into a perpetual buffer).
