I always wondered who wrote this, anyone know? I have my suspicions but ...
".SH BUGS
.I Ptrace
is unique and arcane; it should be replaced with a special file which
can be opened and read and written. The control functions could then
be implemented with
.IR ioctl (2)
calls on this file. This would be simpler to understand and have much
higher performance."
it's interesting in the light of the later plan 9 proc interface.

The manual pages were not yet under SCCS, so the best time gap that I
can give you is that the above text was added between the release of
3BSD (Nov 1979) and 4.0BSD (Nov 1980). Most likely it was Bill Joy
that made that change.
