Status in “openbve” package in Ubuntu: Won't Fix

Bug description:
Binary package hint: openbve

Openbve does not always exit cleanly and may hang on exit.  The Debian/Ubuntu version includes a watchdog that is started during program close and will fire if Openbve has not exited within five seconds;  this uses the FailFast() method.  Output from a hung shutdown appears to be generally stuck somewhere in the audio subsystem:

WatchdogExit: starting timer
WatchdogExit: Something did not shutdown quickly enough, forcing exit

Unhandled Exception: System.NotImplementedException: The requested feature is not implemented.
  at System.Environment.FailFast (System.String message) [0x00000] 
  at OpenBve.Program.WatchdogExit () [0x00000] 
AL lib: ALc.c:1716: exit(): closing 1 Device
AL lib: ALc.c:1640: alcCloseDevice(): destroying 1 Context(s)
AL lib: ALc.c:1650: alcCloseDevice(): deleting 6 Buffer(s)

Ideally Openbve or its dependencies should not hang indefinitely whilst shutting down.
