I've had it happen to me now, and not in a parallel test.   I got this
in t/tab.sh.log:

./pseudotty: getting pty master fd
./pseudotty: unlocking slave device
./pseudotty: getting file name of slave device...
./pseudotty: /dev/pts/8
./pseudotty: entering main loop
./t/Init-intera.inc: line 21: /dev/pts/8: No such file or directory

Maybe if it tries to redirect to the file too quickly, it hasn't been
created properly? I tried running the tests several times again but it
didn't happen again.
