I'm pretty sure that's why I'm using the basic_string template from
interprocess in the first place, instead of std::basic_string.
But I initially wrote that code a long time ago, and now it seems to
be freaking out on me, so.

Hm. In this case, I'm seeing corruption even within a single process,
so I don't *think* this is the problem.
Either way, thanks for taking a look! I'm sure I'm just doing
something extra stupid.
