An app wants to be as responsive to its users as practically feasible, it would try multiple paths to load-balanced resources, and use the first response that come back, then cancel other paths. Cancellation can help reducing vain computation in such architectures, sometimes largely enough.

If not for tight loops or other CPU intensive tasks, you may be interested in Edh, which introduces Go's goroutine to GHC runtime. But Edh threads add much higher overhead on top of GHC threads, so there's a price to pay for simplicity of end programmer's job.

It's briefly described at https://github.com/e-wrks/edh/tree/master/Tour#program--threading-model . This is very new and I'm right now actively working on it for PoC of an STM powered in-memory graph database implementation.

Best regards,
