streaming mode gives harmless database errors #536
Description
TraP gives an error in streaming mode, see below. Oddly enough Trap just continues running and everything works fine. Still we should find out what is causing this. The errors always come from the same threads/processes, one is the sync manager for multiprocessing and the other looks like is a process that uses astropy (using threads). This probably can be solved my making sure no threading is happening before forking (multiprocessing). This is related to issue #519, although now TraP is not crashing anymore.

Unclear if this is still an issue so would be good to test with the latest version.
