Not tested:

- Maybe use the message strings without tr() in the secondary threads, but 
make them translated by NOOP_TR(...). Or if using tr() doesn't result in 
errors but just in untranslated strings in secondary threads, just stay with 
it.
- Push the messages from the secondary threads through tr(...) again in the 
main thread.

Probably this disabled any usage of context/information in the translation, 
but I don't really know.

Have fun,

Arnold
