Never mind, this was a stupid idea -- bash in POSIX mode continues to set
BASHOPTS under `env -i`, so this buys us nothing.

New idea: Terminal allows passing in an environment directly, which is
currently unused. What if we passed the execution environment in through
that, instead of encoding it into the script?
