Nope.

    ilock($b);
    fetch($b);
    iunlock($b);
    ilock($a);
    store($a);
    iunlock($a);

$a or $b may be messed with, but if shared they'll be locked for just as 
long as perl needs to guarantee a consistent state. That lock won't span 
ops, though some ops (eval, or ops with vtable functions written in perl) 
may last a while...
