No idea.

There's already code there to stop the thread (halleluja), but 
apparently only upon LO shutdown 
(connectivity/source/drivers/mozab/mozillasrc/MNSTerminateListener.cxx). 
  Hard to tell for me whether there's some easy and safe way to stop it 
earlier (with the added requirement that it can also be restarted 
correctly later, in case another document is loaded later, and that 
start/stop is race-free in the face of multiple documents being loaded 
simultaneously).

Generally, I would not go near that code (an osl::Condition with 
multiple set/reset is already enough to make me scream, and a missing 
osl_joinWithThread does not raise my confidence, either).

Sounds like the best fix to me, at least for -3-5-0.
