* tests/misc/sort-merge-fdlimit: This test was written assuming that -R typically opens /dev/urandom, but that's no longer the case. Redo test to specify a random source; this resurrects the point of checking for file descriptor exhaustion. Also try plain -R, since that implementation may change in the future too.
