[Haifux] Lecture proposal - high performance multi threaded programming

With a bit of manual reading, anyone can learn how to create a program
that has more than one thread of execution. This breaks down, very
rapidly, however, as the inter-dependencies inside the program start to
burden you down, to the point where you get race bugs that are close to
impossible to find. Fixing those typically involve using the various
locking mechanisms. The result is, more often than not, a program that
both works much slower than the number of threads and processors would
suggest it should, AND at the same time still has race conditions.
This lecture will try to give rules relating to how to construct your
program to begin with so that it will provide high performance, be
maintainable (for some definition of maintainable), and be bug
efficient. In other words, this lecture is about learning to think
"multi-threaded". In fact, efficient enough multi-threaded design do not
even need to have more than one thread of execution......
All in favor say "aye".
