Sorry, I left off a word: I meant "a busybox image." There's a standard
busybox Docker image which I'm testing with via the command I pasted below.
There are certainly ways to configure busybox itself, but it should be
trivial for others to reproduce this error simply by running my series of
commands.

Unfortunately, strace and ltrace aren't available in that Docker image, but
it's a good idea to see if I can get them running there somehow.
