In the case of an I/O bound Web server, I don't think that Go is going to appreciably result in "leaving money on the table". Python releases the GIL on I/O, which is where your time is largely spent.

Linux is very fast at spawning threads. When you're doing I/O, it doesn't matter.
Go's concurrency is not "fundamentally different" from any of the other languages. It's just an implementation of thread-per-connection in userspace. This is an implementation detail, and for a typical Web server I think it doesn't matter much.
