With glib 2.0 you could use g_string_set_size() to reserve a block of
memory that you can read into. E.g., use 

        g_string_set_size (str, str->len + BLOCK_SIZE)

to make sure that there is a block of size BLOCK_SIZE at the end of
the string that you can use. Then read into the memory pointed to by
str->str + str->len - BLOCK_SIZE.
