I see what you're trying to do here, and I appreciate the thought behind
it, and savings in lines of code, but this is not the right way.
Previously, the code distinguished garbage collection, locking
acquisition, and resource-reclamation from each other by using
more, and more meaningful, subroutine names. Also, in the common
case, it collected and reclaimed garbage immediately at the end of
config_detach(9) instead of at some arbitrary time in the future (for
example, in the next call to device_lookup()).
Your change obfuscates the code and needlessly postpones a lot of
garbage collection. Please back it out.
