Thanks for your posting.

We should raise an eyebrow at anything over 5,000 or so.  Now thats not to say that over this amount is inherently bad, just know that there is no free lunch and that a handle to something usually means that on the other end there is a corresponding object stored in NonPaged or Paged Pool which takes up memory.
