No, it doesn't.  I explained your request at #2740 first, and we
discussed the way to solve it (no conclusion yet.)  I'll update #2740
later.

I don't know that single lock solution is acceptable, because the
cross-require issue is caused by developer's error we think, and
should be easily avoidable (Just don't do!)  It would be too big
restriction to save this error.

In contrast to it, autoload can cause unintentional cross-require.  So
I talked to Matz about #2740.

I explained exactly along the same line, not sure Matz agreed or not
though.  Let's keep discussing in #2740.
