- deleteBucket() should be called for cleanup if client abruptly disconnects - out of disk errors should be sent to client properly and also cancel the calls - limit concurrency to available MAXPROCS not 32 for auto-tuned setup, if procs are beyond 32 then continue normally. this is to handle smaller setups. fixes #13834
