Can you provide an example?

I tried using a thread and it didn't work as expected. Here is what I
tried:

    CL-USER> (ql:quickload "qt-tutorial")
    To load "qt-tutorial":
      Load 1 ASDF system:
        qt-tutorial
    ; Loading "qt-tutorial"
    ....
    ("qt-tutorial")
    CL-USER> (defparameter *mythread* (sb-thread:make-thread #'qt-conv::main))
    *MYTHREAD*
    CL-USER>

So far, so good: The window opens and I can evaluate in the
repl. After closing the window, the thread finishes, but it is
impossible, to open a new window. Reevaluating (qt-conv::main)
immediately returns -1 (in contrast to it returning 0 in the first
case after window closing).

In addition, I don't know, how to access the window in the
thread. Would it be feasible to install a polling queue mechanism
(e.g. using Mailbox in sbcl) within the thread which sends to the
application and receives from the repl?
