L2ARC devices of several terabytes filled with 4KB blocks may take 15 minutes to rebuild. Due to the way L2ARC log reading is implemented it is quite likely that for all that time rebuild thread will never sleep. At least on FreeBSD kernel threads have absolute priority and can not be preempted by threads with lower priorities. If some thread is also bound to that specific CPU it may not get any CPU time for all the 15 minutes.
