John Baldwin c4f16b69e1 Add a new 'void closefrom(int lowfd)' system call. When called, it closes ... any open file descriptors >= 'lowfd'. It is largely identical to the same function on other operating systems such as Solaris, DFly, NetBSD, and OpenBSD. One difference from other *BSD is that this closefrom() does not fail with any errors. In practice, while the manpages for NetBSD and OpenBSD claim that they return EINTR, they ignore internal errors from close() and never return EINTR. DFly does return EINTR, but for the common use case (closing fd's prior to execve()), the caller really wants all fd's closed and returning EINTR just forces callers to call closefrom() in a loop until it stops failing. Note that this implementation of closefrom(2) does not make any effort to resolve userland races with open(2) in other threads. As such, it is not multithread safe.
