One other thing. uvcvideo (cheese) does not continue to leak but my
userspace stuff did. I believe that is because uvcvideo uses an urb
pool, so reuses the urbs. I could not, but maybe you can in your app
and that may be a work-around for this leak consuming all memory. This
might be useful if you cannot upgrade your kernel beyond 2.6.27....
