      Reproduced by return of a non-OK status from loader->init()

      Description

      See https://github.com/mongodb/mongo/blob/r3.3.14/src/mongo/db/repl/storage_interface_impl.cpp#L250-L291

      A task runner is created that runs a synchronous task to clone a collection. During execution the task runner ownership is moved to the CollectionBulkloaderImpl ('loader') object on line 285.

      If the call to loader->init() fails on line 289, then the runner will be destroyed, prior to returning from the task. This appears to leave the TaskRunner::runSynchronousTask() call/thread blocked, waiting on its 'waitTillDoneCond' condition variable.
