thanks - this looks fine to me, but i'm still worried about the
nonatomic chain boosting side-effects that i outlined in the previous

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'.
