To give an example, instead of accessing multiple thread objects
simultaneously, GDB has a single global current thread state which it
swaps in and out (using memcpy() and invalidate all). As a consequence
GDB spends its time doing this song and dance where is constantly and
needlessly checks that the current single global thread is the correct
current single global thread.
