-------------------------------------+-------------------------
 The send_data_impl and recv_data_impl functions can enter an annoying
 busy loop if a connection is laggy. Potentially if the connection
 never establishes, this can continue for minutes, until the connection
 times out, having at least one core running at 100% the entire time,
 which is undesirable.

 Adding a usleep(1000) is enough to make sure a torsocks'd program
 doesn't 100% the CPU, and the user likely will not notice a 0.001
 second delay.
