Actually, I think it's probably a separate issue: Roland McGrath wrote
utrace, and he was pretty meticulous about matching existing ptrace
behavior.  It may be a change since the last time I looked at his
patches.

I definitely agree that the current kernel behavior is not very useful.
It may be that the "signal 0" behavior you describe is better, but I'll
let linux-kernel figure that out...

Thanks; hopefully this will be fixed in kernel.org sometime soon.  And
hopefully utrace will be merged, too.
