The use case (reading between the lines) had to do with ping-pong'ing
between /usr/bin and /usr/local/bin though.  And I know that without
checkhash that I used to see that condition too.  But with checkhash
the complaint (from me) went away entirely.  I admit I didn't look at
it in great detail here now because I have had checkhash in use for so
long and not seen this problem since.  I'll need to experiment.
