Yes Torvalds needs a break, but not for what many think. The project can't afford to lose the man to a heart attack.
I retired from IT after 40 years of development and project mgt. When I screwed up I got my a$$ royally chewed up. IT is not a business that runs on unicorns and rainbows. Its dog it dog the higher up you go. Torvalds chews on a few people? Get used to it.
It will get worse. When IT was confined to numbers, checks and invoices it was all fixable. Just a bug. But IT is now well on the way to interfacing with the physical. Bugs could get people killed. That is bugs are quickly becoming the basis for legal torts. There will be no margin for error. Don't be surprised some day when the equivalent of a PE stamp is required to release critical software components.
