.SH BUGS
|
|
The network synchronization between client and server instances is
|
|
weak, and does not prevent incompatible options from being used on the
|
|
two instances. The method used for retrieving work completions is not
|
|
strictly correct, and race conditions may cause failures on some
|
|
systems.
