Actually, never mind. My trivial gdb script is garbage.

I think that even with the fix, it will be fine. Because this test
will just use the regular system call entry tracing point - which gets
the thing right.

It's only PTRACE_EVENT_EXIT reporting that gets it wrong, not the
generic system call tracing case.

I'm not sure if/how you can get gdb to catch that PTRACE_EVENT_EXIT case.

Sorry for my inane noise.
