recv() && MSG_PEEK problem!

[Qing Shen]

Hallo,

I recently fund a problem about recv() and MSG_PEEK which were used in 
ost::SocketPort::Peek(...).

I fund the problem by running "SampleSocketPort". the "peek" function 
can't get the right buffer size.
In my case, it always return 1 as the buffer size.

In fact it's caused by MSG_PEEK. Because it's an unreliable working 
method specially under Windows.

I tested it under several system. Furtunately I only find the problem 
under Windows 20000 professional.

further info. about MSG_PEEK problem can be fund via these links:

I hope some developer can modify this demo and maybe implement it with 
receive() instead of peek().

Thanks,

Qing Shen
