The hash map containers that were being developed by Daniel James (take 
a look at Vault/Containers) used to be shared memory friendly (I mean, 
compatible with Boost.Interprocess). I haven't tested them recently, though.

To share containers between two unrelated processes please see 
Boost.Interprocess (currently in the CVS, and BoostVault/Concurrent 
Programming). Online docs here:
