--- Comment #10 from Kenneth Zadeck <zadeck at naturalbridge dot com> ---
I should point out that this bug could/should have been caught by turning on
the rtl sharing detector that honza wrote many years ago.  I do not know if we
ever did routine testing with this enabled, but it seems like running this in a
systematic way over actively changing ports would not be a bad idea.
