Is not thread-safe. Is exactly as thread safe as a normal STL container 
shared between threads. Only object construction (construction/find,) 
and memory allocation is thread-safe. Shmem containers are STL compliant 
containers capable of using advanced allocators.

So if you want to insert objects in a containers from two 
process/threads, you need to hold a mutex first.
