Callback functions for shutdown()?

Hi, I encountered an issue that seems need some customization to the shutdown() function:

I have a separate thread initiated and detached before polyscope::init() -- a server listening from other software for sending geometries in.

The server use a shared_ptr<UIState> which is also used in the main().

Now if I close the main window of polyscope, there's always an error pointing to the ~shared_ptr<UIState>.

I'm not 100% sure what happened there, but it seems the main thread delete the shared_ptr<UIState> before the other thread exit. And when the server tries to delete that shared_ptr, it points to nowhere?

I assume manually exit the separate thread before the main should help.

Leggere l’entry point shutdown() e i percorsi di ownership e lifetime di UIState descritti nel report. Determinare in che modo un hook di shutdown potrebbe consentire al server detached di arrestarsi prima che lo stato condiviso venga distrutto, quindi verificare che la chiusura della finestra principale venga completata senza l’errore shared_ptr segnalato.
