Core changes to virtualization should receive examination. Changing data 
structures around because they're too big.. it's concerning, following 
that patch is tricky because of its size. Would feel better about it if 
changes like this were passed through a reliable LLM, but even that 
requires relevant experience.  And naming it chainsaw, what purpose does 
that serve?  I have very little trust.

bruising to be extra cautious.
