Android: process crashes (SIGABRT "destroyed mutex") when close() is called while transcribing

Hi, I'm trying to build a little voice keyboard for personal use and I'm running into the problem of my keyboard crashing when I open it quickly after closing it.

Package: ai.moonshine:moonshine-voice:0.1.5 (arm64) Device: Pixel 8, Android 17

Steps to reproduce

Following the usage in the docs and the examples/android/Transcriber sample:

1. new MicTranscriber(context).onText(...).onLine(...); load(); start() on a background thread.
2. Speak.
3. Call stop() immediately followed by close() right after speaking (observed when an always-listening IME service was closed just after dictation).

Expected

No crash.

Actual

The process dies.

Fatal signal 6 (SIGABRT) in tid (moonshine-mic-t)
Abort message: 'FORTIFY: pthread_mutex_lock called on a destroyed mutex'

Thanks for the nice project! Let me know if I'm misunderstanding something.
