Of course, if it does block, you really have no idea whether `stat` calls elsewhere will block because the drives could be arranged in any fashion, and you don't know what's in the cache. The best you can do is make the calls and have the I/O scheduler plan them out in a reasonable way. If you only make one at a time, it's not going to go nearly as quickly. _______________________________________________ Rust-dev mailing list Rust-dev@mozilla.org https://mail.mozilla.org/listinfo/rust-dev
