If I've got a DDP socket open, with one DDPRead call pending, and two or three
packets come in before I can get the data and initiate another DDPRead call,
what happens?  Is the extra data lost?  (I assume)

I suspect I may be in this situation.  What are workarounds?  One thought I
had is having multiple DDPRead calls pending at a time on the same socket...
what happens then?  Will an incoming packet chose one of the DDPRead buffers
(the first one?), the next packet another, etc.?  

Any other possible solutions?  Another protocol perhaps?  For my application
I want to have each socket sending and receiving from several other sockets,
so the connection oriented protocols seem unlikely.  

Thanks in advance.
