This is a long-standing architectural issue that we are finally
within sight of fixing in the abcl-1.2.0 release cycle as we can
benefit from the implementation of MOP to re-root the inheritance
hierarchy when the GRAY streams are loaded.  From what I can tell,
this problem does mess up part of FLEXI-STREAMS, and leads directly
to the inability to run the tests for Hunchentoot to competition.

[A long time ago, Ville collecting some notes on how to go about
this exist in the doc tree][streams].
