When running the btree-split-stress runner, I eventually see this assert:
WT_CURSOR.search: src/evict/evict_lru.c, 82: F_ISSET_ATOMIC(e->ref->page, WT_PAGE_EVICT_LRU)
One thread has found a buffer on the eviction queue without the WT_PAGE_EVICT_LRU flag set:

No other threads in the system are doing anything interesting, they're all sitting in __evict_get_ref waiting on the eviction lock.
So far, I've only seen this failure twice, both times on pixiebob (FreeBSD, 10.2), after about 80 wtperf runs.
alexander.gorrod, michael.cahill, any suggestions about how to chase this one?
