This option has become \fBirrelevant\fR. It was originally introduced
to prevent Tcl from reading beyond the end of a compressed stream in
multi-stream channels to ensure that the data after was left alone for
further reading, at the cost of speed.
.PP
Tcl now automatically returns any bytes it has read beyond the end of
a compressed stream back to the channel, making them appear as unread
to further readers.
