* Make WorkerPools and Queues flushable Adds Flush methods to Queues and the WorkerPool Further abstracts the WorkerPool Adds a final step to Flush the queues in the defer from PrintCurrentTest Fixes an issue with Settings inheritance in queues Signed-off-by: Andrew Thornton <art27@cantab.net> * Change to for loop * Add IsEmpty and begin just making the queues composed WorkerPools * subsume workerpool into the queues and create a flushable interface * Add manager command * Move flushall to queue.Manager and add to testlogger * As per @guillep2k * as per @guillep2k * Just make queues all implement flushable and clean up the wrapped queue flushes * cope with no timeout Co-authored-by: Lauris BH <lauris@nix.lv>
