[$] Zapping pointers out of thin air


Paul McKenney gave a presentation at Kangrejos this year that wasn't (directly)
related to Rust. Instead, he spoke about the work he has been doing in concert
with many other contributors on improving the handling of subtle concurrency
problems in C++.
Although he cautioned that his talk was only an overview, and not a
substitute for reading the relevant papers, he hoped that the things the C++
community is working on would be of interest to the Rust developers present as
well, and potentially inform future work on the language. McKenney's talk was,
as is his style, full of subtle examples of weird multithreaded behavior.

his slides</a> in an attempt to follow along.
