BUGS

69       The network synchronization between  client  and  server  instances  is
70       weak,  and does not prevent incompatible options from being used on the
71       two instances.  The method used for retrieving work completions is  not
72       strictly  correct,  and race conditions may cause failures on some sys‐
73       tems.
