Help me understand racing :) about ioeffect HOT 5 CLOSED

• io1 is forked, so will complete almost instantaneously, not in 10 seconds.
• io2 runs forever, so will never complete.

Thus io2 will be terminated very quickly, after some non-deterministic number of println.

What I think you want is simple X.race(Y), not X.race(Y.fork).

Maybe in this very case it is not the reason, but in general i'd not recommend to try concurrent-ish stuff on the REPL, I see you are using Ammonite, dunno if it is the same as with sbt console but I always get better (expected) behavior when writing a little app in a scala file and using sbt run

Oh! I thought I had to fork at least one of them. This makes sense...

@NeQuissimus Let the types be your guide! 😉 If they allow to do something, then it's a valid operation (or if it's not, then I have some work to do).

@jdegoes .toUnit should have probably been enough of a hint that I need to rethink what I am doing :D
