Unfortunately std::thread is not as capable as pthreads. For example, std::thread has no facilities for controlling the stack size or signal mask.

Whenever I use channels, I find I need them to synchronize with each other. For example, I have a Go data structure with a write channel and a separate read channel; how do I avoid a read-after-write hazard?

The simplest solution is to make them the same channel that ships closures, to ensure requests are processed in-order. But then why not just make all channels ship closures, like libdispatch...
