Just pass the exception object to "print-error-message".

"thread-signal!" might possibly work.

You can of course also do a "thread-join!" in the thread that creates
the thread throwing the error, which would then re-signal the
exception that caused the child-thread to terminate. But that depends
on your use of the stuff.
