[Bug libstdc++/30578] array_allocator can't be safely copied

[bkoz at gcc dot gnu dot org]

Should array_allocator be copy-constructable? I am not sure that the extra
effort to make _M_used shared in a mt-safe manner is worth it, for something
that is supposed to be write-once memory. 

This is a deviation from the normal allocator interface, though.

Interesting.
