Another update, this time to a version that is (probably)
feature complete. Still needs docs and tests.

Also a note to mention that Tk will also need some fixing so
Tk's entrances to the event loop don't end up swallowing
tripped limits; calling Tcl_LimitExceeded(interp) is the
right tactic in those locations.

Looks like the patch to tclMain.c
opens a path of execution where
the master interp will not be
deleted. I think logic should be:

if (!Tcl_InterpDeleted) {
if (!Tcl_LimitExceeded) {
Tcl_Eval("exit");
}
if (!Tcl_InterpDeleted) {
Tcl_DeleteInterp()
}
}
