I'm not good enough with the code yet to see why it's happening... but I
see where it's happening.

Line 416 of app_chanspy.c

414:        if (ast_test_flag(flags, OPTION_WHISPER)) {
415:                ast_audiohook_lock(&csth.whisper_audiohook);
416:                ast_audiohook_detach(&csth.whisper_audiohook); //
lockup
417:                ast_audiohook_unlock(&csth.whisper_audiohook);
418:                ast_audiohook_destroy(&csth.whisper_audiohook);
419:        }

If the spyee channel hangs up, ast_audiohook_detach() will finish, and
ChanSpy will end.

This only happens when there is no audio being generated.
