Where the top of the stack is on x86 (2011)

Exactly-Once Initialization in Asynchronous Python
A common situation in asyncio Python programs is asynchronous initialization. Some resource must be initialized exactly once before it can be used, but the initialization itself is asynchronous — such as an asyncpg database. Let’s talk about a couple of solutions.

You can’t beat a good compiler…. right?
It is extremely well worn conventional wisdom that for your “average” programmer, it’s pretty much impossible to beat a good optimizing compiler at writing fast code.
