In an RTOS of all places, that seems awfully expensive. One generally avoids wasted resources in embedded -- the trade-off is it requires more care during development.
I've never seen RAII work well in an embedded system. Not being able to handle exceptions or errors during destruction ruins everything.

The compiler has no issues "optimizing out" the constructor in my experience. The asm looks just like the equivalent C in all of the cases I've seen.

I mean, we disallow exceptions anyway. And we use RAII for objects where there isn't a weird failure case to be handled like my example of thread priority guards.
