dispatch: change indentation level in _dispatch()

dispatch: change indentation level in _dispatch()

Add an if True: placeholder for a profiling context manager that
will be added in the next commit, for the purpose of reducing size
of the diff due to trivial indentation changes.

This change should be a no-op.
