+ * tClient does not belong here....it's an unneccessary external
+ * dependency.
+ * Except that the server should implement methods to read and
+ * write to sockets and give the possibility to define
+ * a dataAvailable(Callback|Hook) when data comes available.
+ * additinally an acceptHook. Data will be written as soon as
+ * the is date within the writebuffer of the connection and the
+ * connection becomes ready for writing...
+ * No threaded handling neccessary for writes!!! As soon as there
+ * is data to write the server puts the handle into wfds and
+ * whenever the socket it ready for writing data will be written.
+ * This happens as long as there remains data in the writebuffer.
+ * After that the handle will no longer be written to wfds or
+ * it will be closed at all if we define that on request should
+ * have only one answer...maybe we have to create a hook again
+ * to give the client the possibility to trigger a connection end.
+ *
+ * One NOTE: If we want to use preforked workers in future we have
+ * to ffigure out how to handle an open filehandle from one process
+ * to another. To make the worker exchangeable at runtime it needs
+ * to be a shared object or such...
+ * And we need to be careful to define a sane ABI.
+ * !!! Maybe this stuff should then be called connection worker. !!!
