It is not clear what did you mean "ROOT thread".
ROOT system has some class called TThread.
That has not been implemented under Win32 yet.

None can run threads safely unless one knows what "thread" is.
None should use threads unless he/she knows the strong reasons to do so.
None can avoid using CINT within ROOT package.

Nothing happens unless the codes run by different threads have to share
their data. It doesn't matter whether qt "owns the message loop" or not.
On other hand if your threads do not share any data then there is no reason
to create these threads at all. They can be replaced by two independent
processes.
