-Destroying a tracing session stops any tracing running within the
-latter. By default, the implicit man:lttng-stop(1) command invoked by
-the `lttng destroy` command ensures that the tracing session's trace
-data is valid before returning. With the option:--no-wait option, the
-man:lttng-stop(1) command finishes immediately, hence a local trace
-might not be valid when the command is done. In this case, there is no
-way to know when the trace becomes valid.
