[Boost-users] [dataflow.signals][thread_safe_signals] How to alter the Calling of chained signals

Hi! I want to use dataflow.signals, which is build on top of thread_safe_signals. Each call of a producer (each signal) is put into a threadpool. Now i want not to execute the whole chain of data processing at once, but just one chain link at the time and put a new task to the threadpool than. The goal is that i can put rather complex and long (running) dataflow chains in the threadpool, which are divided into many pieces, so the threadpool can often decide which task is most important. So how can i alter the call of the next signal in a signal network/chain? Kind regards Manuel
