yes, it is no problem. i tried this with other packed string
libraries, but at those attempts results was bad because of
inefficiency in my library organization. now i've changed these
internals according to one Simon's idea, and i think that ByteString
I/O will be done with the same speed as low-level character i/o, i.e.
about 100-200 mb/sec on modern cpus (faster than disk I/O by itself :) )
