Okay, but then I have to make sure that my strings won't contain any newline 
characters, right? If this is the case, another question raises up: I am 
using Data.Binary to do the serialization of my data structures to 
ByteString, so does anybody know if this makes guarantees about newline 
characters in the resulting ByteString? 
Otherwise I would go for the "transmit the length of what to expect"-solution.
