BUGS

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