Write the full command to a temporary file for easier re-use. Un-ignore the first stop, this does not seem to be needed in the new async setup. In some cases LLDB is not able to extract the even the top most frame of the stopped thread (happened 2 out of 100 runs of the QDateTime dumper). It's unclear why. For now just report the fact.
