*To patch, or not to patch, that is the question:* Whether 'tis nobler in
the mind to suffer
The loops and branches of speculative execution,
Or to take arms against a sea of exploits
And by opposing end them. To die—to sleep,
No more; and by a sleep to say we end
The heart-ache and the thousand natural shocks
That HPC is heir to: 'tis a consummation
Devoutly to be wish'd. To die, to sleep
