Hi, I'm using cargo-watch 8.1.1 (because 8.3.0 does not work for me). Recently, our build script, which uses cargo-watch under the hood, started looping indefinitely. After debugging it turned out, that when using std::fs::copy("a.txt", "b.txt") on macOS, a file system event IsFile is sometimes emitted on the source file ("a.txt"). The term "sometimes" is better explained here. Our build script is copying some files to target directory, which causes the sources to emit this event, which causes cargo-watch to re-run the whole operation again.

System: macOS Monterey (12.0.1), M1 pro
