With a memory leak, the memory footprint of the running process increases over time. If the conditions that lead to the leak are encountered often enough, the process will eventually run out of available memory, usually causing an exception of some sort. Unless you're in a very specialized environment, the memory associated with the process gets released when it exits. That means that the overall memory on the system doesn't get incrementally consumed over time. So you really only run the risk of the one process running out of memory, not the system as a whole. I hope I've explained that clearly enough.

Some system calls (and some user written functions!) use this to their advantage. On the first call they will allocate some memory, and then reuse it on successive calls. With no cleanup routine, they just rely on the program exit to do the memory release. That's why you might get notice of memory in use at exit when running a program under a memory diagnostic tool like Valgrind. When you trace back to where the memory was allocated, it might be inside something like fopen().
