The only idea that comes to mind is to invent a wrapper for open
(and other affected syscalls) that adds a loop-on-EINTR. Ugly,
and it would not fix third-party extensions until they're recompiled.
My inclination is to regard this as something that's Apple's problem,
at least for now. Perhaps they'll realize what a disaster it is.
(OTOH, they've proven pretty mulish on making SIP usable...)
