+Note (quoted from
+@uref{https://www.kernel.org/doc/man-pages/online/pages/man3/close.3p.html,,man close}):
+``The [POSIX] standard developers rejected a proposal to add
+@code{closefrom()} to the [POSIX] standard.  Because the standard
+permits implementations to use inherited file descriptors as a means of
+providing a conforming environment for the child process, it is not
+possible to standardize an interface that closes arbitrary file
+descriptors above a certain value while still guaranteeing a conforming
+environment.''
