I don't use mtrace, but you can use setBreakpoint() to set a breakpoint
by line number, and presumably you could set the action to whatever will
trigger mtrace. It will modify the source of mymodel so that every time
it creates a new build(), it creates it with a breakpoint within.
See ?setBreakpoint and ?trace.
