I may need a bit more convincing, but let's see the patches: - point against: no wakeup is a bug, possibly hard to find, while an extra wakeup is just annoying. - point in favor: the same argument (multiplied by over 9000) would apply to a wait flag in the request number, but it would be obviously stupid to add a no_wait flag to all requests except the couple that need it.
