Pretty much all the TF-related comments were stale, and
had been for a long time. Fix them up, clean up code.

PT_DTRACE without PT_PTRACED.

Long ago, the "D" in PT_DTRACE meant "Delayed", and it was used
as a flag to mark that we had ptrace'd the process but no longer
did so. That hasn't been true in a while now, and the flag should
probably be renamed, but in the meantime the test for PT_PTRACED
being cleared had been corrupted into something totally nonsensical.

Pointed out by Andi Kleen.

Quieten down compiler warnings, and fix an off-by-one bug when
deciding whether to include the next word.

It didn't allocate space for the final terminating entry,
which caused it to overwrite the next slab entry, which in turn
sometimes ended up being a slab array cache pointer. End result:
total slab cache corruption at a random time afterwards. Very
nasty.

Someone thought it would be clever if proc code ignores removal of
