Comment (by yawning):

 > Seems like Tor does not successfuly kill obfs4proxy when it's no longer
 used. It's unclear why.
 > Maybe obfs4proxy never receives the SIGTERM, or never notices that the
 stdin is closed?

 It's "tor never issues the `SIGTERM`, or close `stdin`".

 As far as I can tell, the `Bridge` directives are always parsed,
 regardless of the `UseBridges` setting, so if a `Bridge` entry exists for
 a transport at all (regardless of it if is used), the PT will always
 exist.

 Removing Bridges with `RESETCONF` doesn't seem to affect `bridge_list` at
 the time when pts would be torn down either.

 All of this is crap is half broken on the tor side basically, and it has
 nothing to do with the process teardown code.
