The sandboxing section of docs/security.md said a putenv() value can't leak "to other requests", which contradicts the worker-mode section just above it: putenv() writes persist across requests handled by the same worker thread until the script restarts. The sandbox only isolates threads. Same wording fixed in docs/internals.md and in the frankenphp_putenv() comment.

Reported by Zachariah Mithani.

Sorry, something went wrong.

Uh oh!
