Description
During eviction of a page, we spend a huge amount of time walking the hazard pointer lists. We even call it twice in the wt_evict path. In profiling, I see we spent 11.3 seconds in wt_evict. Of that, 5.4 seconds was spent walking the hazard pointers in 2 different calls to wt_page_hazard_check. The calls were 2.6 seconds and 2.8 seconds.
