Mobs glitching above fence tops
In SMP, at least, mobs can jump onto the top of a fence, and/or pretend to get out (as seen by clients). If the server keeps running, however, they will return to their pen.

But they can also jump up on the edge of a fence. If the server is stopped with them in the air, they appear to get their location saved as in the air, and on server restart can walk off the fence post out of the pen.

That's the observed behavior: starting up a server, logging on, and seeing mobs turning in circles on top of a fence, and deciding to come down out of the pen. Is this an SMP only bug (as I'm going to mark it on the bug page), or does this reproduce in SSP as well?
