Occasional failures were observed in zconfig.sh because udev could be delayed for a few seconds. To handle this the wait_udev function has been added to wait for timeout seconds for an expected device before returning an error. By default callers currently use a 30 seconds timeout which should be much longer than udev ever needs but not so long to worry the test suite is hung.
