According the Jeffrey's profiling, the penalty is up to 1 second in certain
targets. I think that's a very reasonable wait time if that can improve the
debugger experience, as long as it happens once per user action only in the
cases where there's an extended backtrace via `GetNumExtendedBacktraceTypes`.
IIRC, not all stack traces are sent at once to the IDE. Only one stack trace
gets sent and then, the user needs to expand individual threads to see more
stack traces, in which case 1 second seems reasonable under the circumstances
mentioned above.
