I'm a little worried about whether this could suppress reports that
we do need to hear about. I don't know what TclNRRunCallbacks is
or does exactly, but just going by the name, it seems like it could
invoke non-Tcl code (ie, callbacks supplied by us). It'd be better
to constrain the call stack more tightly, particularly what the top
function is.
I agree that the traces you showed before don't look like our fault.
