I see.  Hm.  I thought that people "just" need to be careful which
"old code" they call.  And if the old code doesn't work, it would get
rewritten.

But I guess the big-lock suggestion leads to bad performance in
problematic cases, whereas my suggestion leads to wrong results in
problematic cases.  And bad performance is better than wrong results.
