0019 is supposed to hang pretty much any linux system out now. I didn't test
it yet, but these guys are pretty reputable.

Paul! Stop breaking the Linux Kernel, pleaze!

Solution: Umm... use Windows? There was nothing much on kernel.org, just some
prepatchs or snapshots which this might not apply to, but their dates are not
past the vuln. date's disclosure. This was at 12/16 02:03 GMT

According to a posts on linux.kernel by Chris Wright the scm problem
has been fixed in both trees and there is a patch for the first problem
that appears to be a good fix but it isn't checked into the bitkeeper
tree yet...
