This is a function intended to be used to wrap database calls such that they perform retrys with exponentially backing off sleeps in between when a DBLockDeadlockError exception is raised. A 'max_retries' parameter may optionally be passed to prevent it from retrying forever (in which case the exception will be reraised). d = DB(...) d.open(...)
