Hello, I've uploaded a new version of defer library to the boost vault. It allows the deferral of functions (function objects == task/jobs) to a thread in the a thread pool, to a new created thread (thread per request) or in the main thread over the same interface. It returns a future object which allows accessing the execution result and catching custom exceptions thrown during execution of the task in the different thread. It uses the future library from Braddock Gaskill (http://www.braddock.com/~braddock/future/ - still under development). kind regards, Oliver
