[Qemu-commits] [COMMIT 9075000] Fix detached migration with exec. |

From: Chris Lalancette <address@hidden>
When trying to do detached migration with exec, I found that
the monitor wouldn't always return in a timely manner. I
tracked this down to exec_start_outgoing_migration. It
appeared we were setting the fd to NONBLOCK'ing, but in
point of fact we weren't.
This bugfix should also go onto the stable 0.10 branch
