From Python 3.4, bytearray is good solution for I/O buffer, thanks to #19087 [1]. Actually, asyncio uses bytearray as I/O buffer often. Whoa what?! This is awesome, I had no idea that bytearray had O(1) deletes at the front. I literally reimplemented this myself on type of bytearray for some 3.5-only code recently because I assumed bytearray had the same asymptotics as list, and AFAICT this is totally undocumented.

Indeed, same here.

Best, -Nikolaus
