Re: Optimization pipeline

[Larry Wall]

There may be some tie-in with STM here too, where a particular
optimization doesn't commit if the optimization gives up in the middle,
or is preempted before it gets done.  But maybe it's all done with
cooperative multitasking.  (But maybe STM is how they cooperate...)

Just a half-baked thought.  It's just when you said "an optimization
completes" I heard "an optimization commits", which implied that an
optimization could also roll back if it needed to.
