This seems to be intention, though it differs from the behaviour of
the `st' driver.

Hmm, there must be a bug somewhere. The following lines of code from
wtopen() are supposed to wait until the rewind is complete:
/* If the tape is in rewound state, check the status and set density. */
if (t->flags & TPSTART) {
/* If rewind is going on, wait */
if (error = wtwait (t, PCATCH, "wtrew"))
return (error);
Once i've got my scratchbox up&running again, i'll check if i can
reproduce this.
Perhaps the driver should be converted to behave similar to `st', even
though i think that wt's behaviour seems to be more convenient.
