Spottedleaf 66554efabb Improve MT-Safety of UserCache (#2080) ...

We were missing a synchronize on a get if cached method, however
it appears that using a ConcurrentHashMap is a better solution
so readers can avoid locking if they just want a cached value.

Existing synchronization for writers remains untouched, the
ConcurrentHashMap is just so readers can safely read without
synchronization
