Yes. But, all of this requires shared state, which requires 
synchronization and/or initialization. Alternatively, each thread 
would be entirely self-contained (and own its personal worker 
process), which avoids those issues entirely. (Perhaps with TLS, 
or better, by making the C++ caller own the state object.)
