// implies that the thread holds the GIL and "detached" implies that the
// thread does not hold the GIL (or is in the process of releasing it). In
// `--disable-gil` builds, multiple threads may be "attached" to the same
// interpreter at the same time. Only the "bound" thread may perform the
// transitions between "attached" and "detached" on its own PyThreadState.
//
// The "suspended" state is used to implement stop-the-world pauses, such as
// for cyclic garbage collection. It is only used in `--disable-gil` builds.
// The "suspended" state is similar to the "detached" state in that in both
// states the thread is not allowed to call most Python APIs. However, unlike
// the "detached" state, a thread may not transition itself out from the
// "suspended" state. Only the thread performing a stop-the-world pause may
// transition a thread from the "suspended" state back to the "detached" state.
