Comment (by embray):
> You were not using bash's built-in test `[[ ]]`
No, I was using bash's built-in test `[ ]`. This is still a bash built-in
--it does not run as a separate process. The only difference between `[
]` and `[[ ]]` is that the latter is bash-specific and less portable. But
when run explicitly in bash, as opposed to an arbitrary shell, `test` is
still a shell built-in.
