Go, data races and combining

Hi,

I continue my work on speeding up Go language. The next major release will feature faster parallel garbage collector, goroutine blocking profiler (enabled with -blockprofile flag) and a lot of other yummy features. Last but not least -- builtin data race detector. Yay! Just add -race flag.

The race detector is based on our ThreadSanitizer technology, which is initially developed for C/C++. Now that both C and C++ standards have multithreading support, data races officially banned as "undefined behavior". You can read my essay on data race here.

If you are subscribed to this blog, you are probably interested in synchronization and concurrency stuff. It's not that I am writing a lot lately, but here is at least something new -- Combiner/Aggregator Synchronization Primitive.
