//! The probe test of `no_threads_child_test_support.rs`.
//!
//! What: one test, `thread_probe`, that tries to start one thread and prints whether it could.
//! Why: `ran_in_child` starts it first in a child whose process limit is one; if a thread still starts there,
//! this user may exceed the limit, so the real test is skipped instead of proving nothing.
//! Run without the child's environment variable, the probe returns at once and checks nothing.
//!
//! In TS you'd write (pseudocode):
//! ```ts
//! test("thread_probe", () => {
//!   if (!process.env.CLI_GIT_NO_THREADS_CHILD) return;
//!   console.log(canStartThread() ? "thread-started" : "thread-refused");
//! });
//! ```

/// Says whether one thread can start in this process, in a child under the limit. A test run without the variable does nothing.

    println!("{}", if started { "thread-started" } else { "thread-refused" });
