Maybe when there are more than one transfer, the application call curl_multi_perform or curl_multi_socket_action more frequently.
This is indeed wrong usage, as the calls should be done according to events (socket/timeout).

Please give us more details when you call curl_multi_perform/curl_multi_socket_action from your code (what is the trigger to those calls), and when you call it with CURL_SOCKET_TIMEOUT...
