All the complexity is in libdill, which is written in C: http://libdill.org/ http://libdill.org/ ... which means they buried the lead pretty deeply, because libdill is an interesting little library: Structured Concurrency in C! From the FAQ: http://libdill.org/faq.html http://libdill.org/faq.html > How does libdill's concurrency differ from Go's concurrency? > No interaction between threads. Each thread is treated as a separate process. > Channels are always unbuffered. > choose, unlike select, is deterministic. If multiple clauses can be executed, the clause closest to the beginning of the pollset wins. > chdone signals the closing of a channel to both senders and receivers. > Coroutines can be canceled. And: http://libdill.org/structured-concurrency.html http://libdill.org/structured-concurrency.html > What is structured concurrency? > Structured concurrency means that lifetimes of concurrent functions are cleanly nested. If coroutine foo launches coroutine bar, then bar must finish before foo finishes.
