is unknown, `0` is returned.

It is not unusual for this value to be less than or greater than `os.totalmem()`.
This function currently only returns a non-zero value on Linux, based on cgroups

This sentence is worded a bit confusingly. What is the value on Windows?

The description was copied from the Libuv documentation.

That may be true but it's still confusing as is. Not sure I have a better suggestion tho

Two suggestions:

  1. Maybe add an Experimental marker to the docs. Libuv's implementation changed in the not too distant past and it may change again

  2. Implementing it as a fast API is probably overkill. The limiting factor is the amount of file parsing libuv has to do. And also, you're probably not going to call it 1,000x/sec.

Thanks for suggestions, Hi @anonrig, would you mind taking a look at the second suggestion. Thanks !

I agree that it is an overkill, but I don't see any downside of adding fast API. This might be important/valuable functionality which result in high usage (for example APMs). But if @bnoordhuis or anybody disagrees with it, I'm fine with removing it.

I don't see any downside of adding fast API

From what I read in #46199, the fast API would only be triggered if the function is called in a loop with a high iteration count. Unless that's something we expect, the fast API would be a function with little to no usage.
