Comment (by dcf):

 Replying to [comment:5 ahf]:
 > I think the example script have a bug: The `echo`'s in the subshell
 writes to standard out and you redirect all output from the subshell from
 standard error to standard out, where instead it should be redirect all
 output from the subshell's standard out to standard error, so `1>&2`
 instead of `2>&1`.

 You're absolutely right. It was my mistake. I apologize for the false
 report.

 > Tor's PT standard error handler does not send the standard error
 messages into the PT state machine handler and logs the errors with the
 warning log level. I do think that's a bit higher than what we want for
 this kind of event, so I'm submitting a patch in a moment that lowers the
 log level for PT standard error messages from warning to debug.

 Could we rather close this ticket immediately and do the log level in a
 separate ticket?
