I did.  Hence the reference to the "tiny quiescence bug" in my quoted
paragraph above.  :-)

I hope so.  YBWC isn't only almost as easy as sharing the hash table,
it is also much more fun!

You're welcome.  :-)

For the benefit of those who were *not* here when it all started, I'll
give a brief summary:

I assume that everybody has heard about Deep Blue.  IBM also had
a light-weight version of Deep Blue, running on a much lower number
of processors, which they decided to call "Deep Blue Jr".  The Junior
team became furious because they felt that IBM tried to steal their
name, and some extraordinarily stupid and unnecessary flamewars
about the topic arose in the CCC.

A while later, in what to all neutral observers looked like a
mind-bogglingly childish attempt to make a point (I'm not sure
that's what it was, but it certainly looked so), the first parallel
version of Junior was released as "Deep Junior".    To my amazement,
this almost instantly became the standard naming convention for
parallel versions of previously single-threaded programs.  It didn't
last long before Deep Shredder, Deep Fritz and Deep Sjeng appeared
on the scene.
