Right, you won't block, but you can bring your system to a virtual
standstill via paging if you try to put more data into a socket
buffer(or program memory) than you have available memory. (assuming your
disk is much faster than your connection speed to the receiver) Also,
even if the socket operation isn't blocking, the file operation is. So
if your curl_handle is pulling data off a drive, it will block for as
long as that operation takes(which can be a long time for a large file).
