There is one argument against threading: You should not use Threads in J2EE
controlled environments.

Making it configurable is a good idea. We can have different behaviour for
different environemnts (e.g. singlevm mode, C/S mode, running within a J2EE
app server ...)

I like your suggestion very much. We need exactly this kind of refactorings
to improve the overall code quality!
