Has anybody launched this in a VM under Xen and/or EC2 to see if AWS is vulnerable? If this can mangle the Dom0 over a paravirt DomU, this would be awfully interesting.

/me off to test...

update: Would be nastier if it forked cpux2 times or something at startup. My test server is running fine for 15 minutes with it active. A bit slow, but still responsive and accepting new SSH connections. Server is Centos 5.5 with 2.6.18-194.26.1.el5

Proc net unix seems stable as below, maybe slowly growing now.

[root@xenpig net]# cat /proc/net/unix | wc -l

153406

I have kill -9 that process several times though, and it ain't dying, so that is an issue.
