hi,

this is exactly how it works. i have added simple abstraction that works 
like java InputStream: you can request bytes from input and it will 
block until byte is read or there is error (such as timeout) when 
reading from socket.

i am wrapping now C++ version pf XPP3 so it passes some first unti 
tests. as soon as i have it i wills send it to you .

thanks,

alek
