With the caveat that I think this is O(N) in the length of the list,
with comparison operations at each step.  I think 'del alist[i]' is
also O(N), but amortized and with  *much* smaller constant (only cheap
internal pointer shuffling, without any real Python work).

Someone with better knowledge of the list object internals, feel free
to correct the above (I'm actually curious if the reality is
different).
