whoopee!. Bleh. Really a security issue? Same thing happens if you have

windows content enabled and you drag around a window, as long as your
dragging the window, the cpu will remain close to 100 % usage.
Significant?

Probably not directly, but possibly indirectly.

The questions are, of course:

1) Is the 100% cycle sucking done as a pre-emptible thing, or can you
cpu-starve something else using it?

2) Is there some *other* security-related API that botches incorrectly if
it's
cpu-starved?

No, unless its proof of some shoddy coding of some-sort.

A hammer is a useful tool for finding  non-impact-resistant screws......
