It seems a bit absurd to add a dependency on instructions on the other side of another barrier... Maybe we could go ahead and schedule pending instructions when we see a barrier instead of doing all of this work?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
