Vladimir Blagojevic updated ISPN-1546:
--------------------------------------
Comment: was deleted
(was: Sanne, I made a thread-safe, that is, fail-safe iterator for FastCopyHashMap. One
would use it by instantiating FailSafeFastCopyHashMap instead of regular FastCopyHashMap.
Should we use it only for FGAM? Look at AtomicHashMap and let me know what you think is
the optimal solution giving you and others enough flexibility! Preview of this change is
here https://github.com/vblagoje/infinispan/compare/master...t_1546_m)
