In Perl, setting $/ sets the string that is used as the "record separator," which sets the boundary that the `<>` construct reads to. Setting `local $/ = 0666;` evaluates the octal, getting 438, and stringifies it. Thus, the later read from `<CHLD_OUT>` stops as soon as it encounters the string "438" in the watchman output, yielding invalid JSON; repositories containing filenames with SHA1 hashes are able to trip this easily. Set `$/` to undefined, thus slurping all output from watchman. Also close STDIN which is provided to watchman, to better guarantee that we cannot deadlock with watchman while both attempting to read.
