The callable is allowed to block, but the C{onResult} function must not block and should perform as little work as possible. A typical action for C{onResult} for a threadpool used with a Twisted reactor would be to schedule a L{twisted.internet.defer.Deferred} to fire in the main reactor thread using C{.callFromThread}. Note that C{onResult} is called inside the separate thread, not inside the reactor thread. @param onResult: a callable with the signature C{(success, result)}. If the callable returns normally, C{onResult} is called with C{(True, result)} where C{result} is the return value of the callable. If the callable throws an exception, C{onResult} is called with C{(False, failure)}. Optionally, C{onResult} may be L{None}, in which case it is not called at all. @param func: callable object to be called in separate thread @param args: positional arguments to be passed to C{func} @param kw: keyword arguments to be passed to C{func} Nc>TR5nSnSTlTRbTRX5 STlgU(d[R "U5 gg![a [5nSnNdf=f)NTF)theWork BaseExceptionronResultrerr)resultok inContexts rr6ThreadPool.callInThreadWithCallback..inContext sw "**, !%I !!-""2.%) "!   sA!!A:9A:c:>[R"TT/TQ70TD6$r)rcall)rctxrrEsr5ThreadPool.callInThreadWithCallback..s#GLL % % "% r!r#None) rlrtheContextTrackercurrentContextcontextsrrrNdo)rrrrrErrs ```@@rr#ThreadPool.callInThreadWithCallbacksXH ;; ''668AA"E $ &  i r!cSUlSUlURR5 URHnUR 5 M g)z) Shutdown the threads in the threadpool.
