I'm no expert on this but I don't think you can catch it directly there. I think you \
need to catch it in the thread and then send a signal. But that should not be a \
problem since the handling can still happen in the mainthread.

no, what I want is to catch the exception in the main thread!

You could just catch the exception within the thread and send a signal to the \
main-thread.
