Not terribly long ago I went digging thru GCC docs on the hope of 
finding an __attribute__ for quickly and cleanly applying an "atomic" 
property to a variable. Didn't find one. But knowing there were 
"packed" and similar attributes for structs, and the various things 
done for AVR registers, led me to suspect "atomic" or similar might 
exist.
