Terminal tests currently require libc just to set/unset env vars, which changes the threading implementation used in tests versus production (for instance). pthreads in tests; build uses raw clone().
Tests also mutate global process env, which is not thread-safe and can cause flakiness.

To drop the libc requirement we can allow Terminal to accept EnvMap so tests don't touch process env.
