thrash

( vi.)

   To  move  wildly or violently, without accomplishing anything useful.
   Paging  or  swapping  systems that are overloaded waste most of their
   time  moving data into and out of core (rather than performing useful
   computation)  and  are  therefore  said  to thrash. Someone who keeps
   changing  his  mind  (esp.  about what to work on next) is said to be
   thrashing.  A  person frantically trying to execute too many tasks at
   once  (and  not  spending enough time on any single task) may also be
   described as thrashing. Compare {multitask}.
