If the NonStop opendir() does not open a directory fd under the hood,
then maybe we should wrap opendir() so that the gnulib rpl_opendir()
always opens a directory at the same time; at which point the gnulib
rpl_dirfd merely returns that directory fd.

Also, does NonStop have anything like Linux' /proc/self/fd or lsof, for
reverse engineering which fds a process has open and on what files?  Is
there an equivalent to strace functionality for tracking all syscalls
made by libc?
