There’s a recent promising development relevant to the GC pause issue. It seems couple weeks ago some smart developer working for Microsoft has made a version of GC called “Satori” which pretty much solved these GC pauses for many real-world use cases.

I don’t yet have hands-on experience with that Satori GC, though.
