[wpkg-users] [Bug 42] add a time parameter

Just to make the decision simpler between mailslots and named pipes.

Some developers choose to use named pipes instead of mailslots for 
interprocess communications. Named pipes are a simple way for two 
processes to exchange messages. Mailslots, on the other hand, are a 
simple way for a process to broadcast messages to many other processes. 
Another issue in the choice between mailslots and named pipes is that 
mailslots use datagrams, and named pipes do not. A datagram is a small 
packet of information that the network sends along the wire. Like a 
radio or television broadcast, a datagram offers no confirmation of 
receipt; there is no way to guarantee that a datagram has been received. 
Just as mountains, large buildings, or interfering signals might cause a 
radio or television signal to get lost, there are things the sender has 
no knowledge of that can prevent a datagram from reaching a particular 
destination. Named pipes are more like simple one-to-one telephone 
calls: you can talk only to one party, but you know that the 
conversation is occurring. So, if an application requires guaranteed 
reception, it  should use a named pipe; but named pipes cannot 
broadcast. Mailslots do not guarantee reception, but they can broadcast.
