A shared hash in list context (my @a = %testOne) counts as modifying its internal iterator, too? (@a size will get 10,4,12,18 or whatever). And neither such assignment nor keys built-in are "atomic" thread-wise then, and it's not a bug? Yes, using a lock helps. In scalar context it evaluates to 1, not to number of keys. Not documented anywhere, neither.
