I'd like to point out that using unpinned memory for your ByteString
alternative means you aren't providing the same API: as most string-using
foreign functions expect something more like a bytestring than a Haskell
string or text type, ByteString is pinned specifically to support that use
case directly and many users of ByteString expect that support. This will
include the ByteString variants of various functions in the "posix"
package, which are thereby providing "raw" versions of system calls,
ensuring the Haskell program can get exactly what the OS provides (POSIX
interfaces don't use Unicode, thus various Unicode encodings can be unable
to provide the exact OS level representation of e.g. file names).
