 When repeated running the Android `TorService` test suite from
 https://gitlab.com/eighthave/tor-android, I occasionally received this

       main  src/feature/hs/hs_circuitmap.c:598: hs_circuitmap_init:
 Assertion !the_hs_circuitmap failed; aborting.

 * I think this only happened if Tor quit the test before due to bad
 command line args
 * it could be that the Android Test Orchestrator is reusing state that it
 shouldn't be https://developer.android.com/training/testing/junit-runner
 * "The Dalvik process hosting a typical app is forked off of zygote with
 all the common android libraries already mapped, so new unique copies
 don't have to be opened" https://stackoverflow.com/questions/9153166

 > 2) tor is busted and is calling hs_circuitmap_free_all() less than it
 should there are probably more, like:

 restart tor before it has shut down
