What does R.do_all do?

@jots just found this and after a quick peek it looks like it's only the IO operations that are run async, á la node.js :). That means that reading the file system, doing database calls etc will allow another fiber to do its work.

Would you mind describing what R.do_all is doing?

@ioquatix or perhaps I got it wrong?

@sandelius Even reading from the file system will block the entire reactor. There are trade-offs in the design of such a system and also limitations within Ruby itself. Ideally, we could yield while reading from the file system. In practice, network operations are the highest latency.

@ioquatix ahh sounds fair

It's trivial enough to design a thread pool to handle blocking / computational workloads, e.g.
