Thanks for the help. I investigated the problem.

It seems that some query threads don't seem to terminate. This behavior
occures with modules that use to connect to the internet (yahoo) and the
programs module causes this, too.
Because the worker thread is still working on executing a previous query
it's busy. If I type in a new query, another working thread will be
blocked with this task. Eventually, all worker threads are blocked and
new queries are queued and no new results will be displayed.

Now I try to find out whether the ThreadPool or the module itsself is
responsible for this.
