2.4+ptrace exploit fix breaks root's ability to strace

Hi,

Are the authors of the ptrace patch aware that, in addition to closing the
hole, the "fix" also prevents a ptrace-capable task (eg, strace started by
root) from ptracing user threads?

For example, you can't strace vsftpd processes started from xinetd.

Is this intended behaviour?
