I'm doing mostly embedded work on ARM chips at the moment. Which is a world away the rooms of Sparc V9's I've also worked on. It's a tighter space and you can't use too much of C++'s bigger bits. But multiplexing an SPI bus with C++ for example was vastly more efficient coding and performance wise because you don't need to remember whether some function or other set a mutex and released it. A specific custom lock in the base class improved code review and mutability. It has it's uses.
