The completion system tests in "make check" rely on zpty, so it's quite
definitely not borked in the general case.  However ...

} $ zpty x cat

} $ zpty -r x

A quick check with "ps"/"strace" indicates that "cat" is being stopped with
a TTIN signal.  That's kind of odd, it means that in spite of being on a
new pty it is not being "attached" to that tty as group leader.  I would say
this is in fact a bug in zpty.
