> *Problem*
> When key is updated with new value and new expiry policy, old entry is not removed from
"pendingEntries". It leads to excessive memory consumption.
> *Steps to reproduce*
> 1) Create a cache
> 2) Put a lot of entries with same key, but different expiry policies one by one.
> 3) Observe trashed "pendingEntries".
> Concrete fix is to be defined.
