Everything is limited, some processors are more limited than others  :).
Seriously, I think this should be discussed in a language standards
comittee area rather than inside GCC's development since right now GCC
is correct.  I don't want to limit GCC's output to "thread safe"
optimizations.

In fact any optimization that changes order of loads/stores is not
thread safe.  So you just disabled every high level optimization.
