Hello all,

As an aside, if anyone is interested in techniques for making atomic
transactions fast with low latency, etc, the paper

Atomic heap transactions and fine-grain interrupts by Olin Shivers,
James W. Clark and Roland McGrath:
http://www-static.cc.gatech.edu/~shivers/papers/heap.ps

presents several *neat* hacks to do this efficiently.  I'm sure that
the implementators on the list are already aware of this work, but I
just wanted to point it out as interesting reading for people (like
myself) who think this stuff is neat but don't necessarily have broad
experience with it.

Will
