+socket.<b>select(</b>recvt, sendt [, timeout]<b>)</b>

+
+<p class=description>
+Waits for a number of sockets to change status. 
+</p>
+
+<p class=parameters>
+<tt>Recvt</tt> is an array with the sockets to test for characters
+available for reading. Sockets in the <tt>sendt</tt> array are watched to
+see if it is OK to immediately write on them.  <tt>Timeout</tt> is the
+maximum amount of time (in seconds) to wait for a change in status.  A
+<tt><b>nil</b></tt>, negative or omitted <tt>timeout</tt> value allows the
+function to block indefinitely. <tt>Recvt</tt> and <tt>sendt</tt> can also
+be empty tables or <tt><b>nil</b></tt>. Non-socket values in the arrays
+will be silently ignored.
+</p>
+
+<p class=return> The function returns a table with the sockets ready for
+reading, a table with the sockets ready for writing and an error message.
+The error message is "<tt>timeout</tt>" if a timeout condition was met and
+<tt><b>nil</b></tt> otherwise.  The returned tables are associative, to
+simplify the test if a specific socket has changed status.  
+</p>
+
+<p class=note>
+<b>Important Note</b>: a known bug in WinSock causes <tt>select</tt> to fail 
+on non-blocking TCP sockets. The function may return a socket as
+writable even though the socket is <em>not</em> ready for sending.
+</p>
+
+<p class=note>
+<b>Important note</b>: calling select with a server socket in the receive
+parameter before a call to accept does <em>not</em> guarantee
+<a href=tcp.html#accept><tt>accept</tt></a> will return immediately. 
+Use the <a href=tcp.html#timeout><tt>timeout</tt></a> 
+method or <tt>accept</tt> might block forever.  
+</p>
+
+<p class=note>
+Interesting note: as mentioned in some manuals, calling select with both
+sets empty and a non-null timeout is a fairly portable way to sleep with
+sub-second precision.

+<em>chunked transfer coding</em>, closing the socket when done;
+<li> <tt>"close-when-done"</tt>: sends all received data through the
