commit e3ed06579bd8129c11af0a1636a55d62af08980b
Author: David Brownell <dbr...@us...>

    Cortex-A8: parts of examine() run just once
    
    The examine() method has some conceptual breakage.  Cope
    with it by manually splitting out the run-once parts from
    the after-each-reset parts ... this gets rid of memory
    leaks and speeds up resets after the first one.
