It depends on one's definition of "easy". One complication is that some shells close fd 5 automatically; for these shells there was no bug and the fix is a no-op. Another complication is that there's no portable way in the shell to detect whether fd 5 is open. Modulo portability problems like this, it should be possible to test for regression in the future, at least on Linux-like hosts.
