Rollup merge of #109225 - seanlinsley:patch-1, r=ChrisDenton
Clarify that RUST_MIN_STACK may be internally cached For larger applications it's important that users set `RUST_MIN_STACK` at the start of their program because [`min_stack`](https://github.com/rust-lang/rust/blob/7d3e03666a93bd2b0f78b3933f9305832af771a5/library/std/src/sys_common/thread.rs) caches the value. Not doing so can lead to their `env::set_var` call surprisingly not having any effect. In my own testing `RUST_MIN_STACK` had no effect until I moved it to the top of `main()`. Hopefully this clarification in the docs will help others going forward.
