Looks good except for a couple of minor points.

Does 2 lookups on the strRequest map when one would suffice.

You might want to add a private do nothing copy constructor and assignment operator to prevent copying this object, since copying the mutex would probably not be good.

Turned out that current implementation doesn't really help to mitigate abuse - when connection is closed CNode object is destroyed and removed from nodes vector meaning that all "fulfilled" info is gone too. Such info wasn't preserved on wallet shutdown either so client wasn't able to prevent banning of itself by other nodes. Basically the whole thing wasn't working.
This PR implements a separate manager for fulfilled requests
CNetFulfilledRequestManagerwhich fixes issues described above. This also removes testnet/mainnet specific logic for such cases by introducing additional chain paramnFulfilledRequestExpireTime(60 minutes for mainnet, 5 minutes for testnet).
