Makes me wonder if we should be marking these fds with FD_CLOEXEC to solve the issue in a way that is platform agnostic. It may turn out that we'd be better off to make it an explicit choice by the parent when it leaves a FD open while spawning a child process (and by that spawned child when it runs another executable---but I undertand that it is a single-step operation, not a two-step one, on Windows). In any case, synchronizing the differences in compat/ between our trees is good. Queued.
