Kevin, when you make a socket connection to the server, are you used
blocking or non-blocking?   A blocking connection won't proceed until
it gets a response, while the non-blocking will - and perhaps your
problem lies there.  your 2nd command gets a response before the first
one comes back.

Does indeed your problem only happen at the beginning, or can it
happen anywhere in your list of files?
