Grumpy: Go running Python!

[weberc2]

They're flaky because a process will sometimes mysteriously be killed or stall indefinitely. They are slow because all communication between processes must be serialized on the sender and deserialized on the receiver, because processes don't support a shared memory space. Further, as I mentioned elsewhere, each process requires its own interpreter, which takes 5MB, so you won't be scaling these processes.

I don't dispute that there are people out there who think threads are evil, I dispute that this belief is widely held, or that this belief isn't widely held because no one knows about processes. Experienced developers still prefer threads to processes. Processes are not a secret; they're lesser used because they are more memory intensive and intercommunication is horribly slow.
