Choosing a delimiter is tricky, since it means that character
is no longer allowed to appear in any strings.  The most often
chosen options would be LF, CR/LF, or whitespace.  If you use
LF or CR/LF, then you can just call readline() and get the next
string.

When designing an application protocol to run on top of TCP, it
can be very handy to keep it in readable ASCII with CR/LF
delimited lines (e.g. SMTP, IMAP, POP, NNTP, ...)
