title: Can valgrind output partial reports without having to quit the profiled application?
body: <p>I want to check a long running process for memory leaks with valgrind. I suspect the memory leak I'm after might happen only after several hours of execution. I can run the app under valgrind and get the valgrind log just fine, but doing so means I have to quit the application and start it again anew for a new valgrind session for which I would still have to wait several hours. Is it possible to keep valgrind and the app running and still get valgrind's (partial) data at any point during execution?</p>
