tdebug(+ThreadId)

Prepare ThreadId for debugging using the graphical tracer. This implies installing the tracer hooks in the thread and switching the thread to debug mode using debug/0. The call is injected into the thread using thread_signal/2. We refer to the documentation of this predicate for asynchronous interaction with threads. New threads created inherit their debug mode from the thread that created them.
