Generally speaking, your user interface should not be managed by the
same thread that any long-running process acts in. Without knowing
more about your application and platform I can't really say anything
further that's of help, but separating them out might allow you to
ignore this completely (having running searches the user can come back
to later), or manage things a little differently (if you don't use
remote backends, having a dedicated thread that runs searches, which
you can kill; but create the Database object in a separate thread).
