I disagree with Hubert here, but that's what makes life fun.

As Bill Sommerfeld explained in a different piece of mail, there's
considerable work involved in doing any form of SMP.  Personally, I've
always been a proponent of the "small steps" approach, rather than the
"big bang" method, and I think this is yet another example where we
should walk before we run. Sure, the aim is fine-grained locking, but
I'd like to get there, and, as a means of achieving the aim, biglock
would seem to be a good way of getting there.
