 chutney hs verify hangs under the latest tor 0.2.7-alpha-dev.
 Verification of clients, exits, bridges and IPv6 bridges works fine.

 hs verify worked in 01d988d72f9eae798a36d1c8bb226b9e8f4fe3f1 (after
 teor/bug-15642-v3-fallback-unit-tests was merged), but now hangs in
 63a90f2df4dcd7fff862ca3849f3aa3b1dec7e84.

 This may be due to:
 * dgoulet's changes in #14845 or #14847,
 * andrea's changes in #14840,
 * nickm's changes in #15546, or
 * cypherpunk's changes in #15546
 which were merged in between those commits.

 It worries me that we may have broken hidden services, so I have listed
 this as "critical".

 I'll look into this when I get time in the next day or two, but I wanted
 to log the bug so everyone knew about it.
