Yes. We move a bunch of globals into a "struct thread_state" -- specpdl
stuff, gcprolist, catchlist, etc. I haven't yet done an audit of
globals to see whether we caught them all. These are also redefined
using the preprocessor, e.g.:
/* Recording what needs to be marked for gc. */
struct gcpro *m_gcprolist;
#define gcprolist (current_thread->m_gcprolist)

I will think about your other points and reply later.
