The scheduler resources necessary for a thread are insignificant due to the ~8K RES (4K in userland, 4K overhead) and 8M VIRT required for the stack. Linux/FreeBSD are also fully capable of scheduling a very large number threads. _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
