Right.  I can't say as to whether or not that was the leak in
`mouse-position', but if it stabilises then I guess it isn't a problem
anymore.

That's quite odd, but I suspect a memory fragmentation issue if you have
lots of frames (or child frames) and frequently resize them.

What if you turn off all packages that utilize child frames?
