In that case a conversion of a conditional branch to an unconditional
write to a visible variable is not an acceptable behaviour. Aside from
the kernel issues, it would break any number of threaded userspace apps.

As was mentioned elsewhere, it's akin to sprinkling

int j = i; i = j;

throughout the code. If "i" is accessed by multiple threads, this is
not allowed unless a lock is held.
