/**
* It's not allowed to call synchronoues back inside an oneway interface call.
* (see IOnewayLink too). So we start a thread (implemented by this class), which
* gets all neccessary parameters from the original called object and
* call it back later inside his run() method. So the execution of such oneway call
* will be asynchronous. It works in a generic way and can be used or any type
* of oneway request. Because the source and the target of this call-link knows,
* which method was used and which parameters must be handled.
