Wow! Looks like there were a lot of simplifications you could make in there.
Very cool. I'm also glad it wasn't too difficult to fix up that code.

You could do something like this:

    svn_string_t string;

    string.data = StringValuePtr (aStr);
    string.len = strlen (string.data);
    err = svn_txdelta_send_string (&string, ...);

In other words, you don't actually have to allocate the string structure on
the heap. You just need to pass a pointer to the _send_string() function.

Cheers,
