I'm saddened by this. My code has two copies of every `unique'
string: one for C code and one for Lua code. I use the C interface
because it's extremely fast, and I can't find an obvious way to use
the Lua unique-string table from C. (I don't want these strings
garbage-collected.) I'm probably missing something. What?
