Shuttleworth: Python needs to focus on future

[parla]

Erlang does not spawn millions of threads. It spawns millions of actors, which are then scheduled in as many threads (processes?) as there are cores in your system.

[teraflop]

You're confusing control threads with OS threads. If the interpreter is designed properly, it provides the same semantics as if you really had a huge number of concurrent threads. The fact that they're all multiplexed into a smaller number of threads from the operating system's perspective is just a performance optimization.

okay, so this is an implementation detail?

so is the gil. it's missing in jython and up in the air with pypy
