* Add custom panic hook. Print backtrace and thread, error info on panic. * use sync_channel and SyncSender * nit fixes and cleanup * disable custom panic hook while running tests * make separate errors.rs file and address other review comments * improve panic message * debug: does increasing time between snapshots make tests pass? (this is temporary) * fix(tests): suspend before sending quit command * fix(tests): add missing use * style(format): commas are important apparently * fix(tests): can we get away with reducing the QUIT suspense time? * fix(tests): can we get away with 50?
