----------------------------------------------------------

OK, so Cipher is not reentrant, so we cannot use it from multiple threads. Both encrypting and decrypting a message is synchronized, so we cannot do this in parallel.
However, we could create a pool of Ciphers for parallel encryption / decryption...

> A stress tests with the following setup showed that performance (reads and writes/sec) is halved when ENCRYPT protocol is enabled:
> Infinispan had distributed sync cache with 2 owners on 4 nodes, no transactions. The stress test used 10 threads on each node accessing 1024 byte entries, no conflicts on keys, 20 % writes, 80 % reads. 
> It would be great if we could improve the performance of ENCRYPT protocol.
