Description
We don't want users to hit asserts if we've leaked memory references on shutdown. For instance:
-1> 2017-10-04 18:00:36.061972 7fdffe78d800 -1 leaked refs:
dump_weak_refs 0x5595a82d8cb0 weak_refs: 207607 = 0x5595ca644480 with 2 refs
0> 2017-10-04 18:00:36.063904 7fdffe78d800 -1 ./common/shared_cache.hpp: In function 'SharedLRU<K, V, C, H>::~SharedLRU() [with K = unsigned int; V = const OSDMap; C = std::less<unsigned int>; H = std::hash<unsigned int>]' thread 7fdffe78d800 time 2017-10-04 18:00:36.061988
