thanks - this looks fine to me, but i'm still worried about the nonatomic chain boosting side-effects that i outlined in the previous mail.
the tempting property of your patch is the fundamental reschedulability of the boosting itself - and the resulting simplicity of locking. On the con side, i dont see how we can detect deadlocks reliably, nor how we can avoid 'incorrect boosting' (outlined in the previous mail), if the chain gets 'broken'.
