What patterns of use are 'safe' - can distinct instances be used on
separate threads?  Or one instance shared between threads?  Is the
client code required to acquire/release locks before modifying, ...

Sorry, do you mean the library doesn't call the thread library and the
client code may need to when sharing 'something' between threads.

Sorry, do you mean the library does call the thread library and the
client code needn't when sharing 'something' between threads.
