Hi,

Yep. Right now the stringbuf goes into read-only memory, but the string
itself goes in writable memory as it needs its link to the stringbuf
fixed up (relocated) at runtime.

That can happen already, but I think if we do texinfo we should
serialize the string as texinfo -- that way no relocs are needed if
docstrings aren't used, because if we use the .docstr string table, it's
just an offset into the image of a NUL-terminated UTF-8 byte sequence.
(I suppose we should be careful about embedded NUL characters; perhaps
we should use some other format for the string tables.)
