title: How much memory is my windows app really using?
body: <p>I have a long-running memory hog of an experimental program, and I'd like to know it's actual memory footprint.  The Task Manager says (in windows7-64) that the app is consuming 800 mb of memory, but the total amount of memory allocated, also according to the task manager, is 3.7gb.  The sum of all the allocated memory does not equal 3.7gb.  How can I determine, on the fly, how much memory my application is actually consuming.</p>
  
  <p>Corollary:  What memory is the task manager actually reporting?  It doesn't seem to be all the memory that's allocated to the app itself.</p>
