In all but a few cases, the data structures created and used by this library are not thread-safe. Therefore, they should not be shared across threads.

The exception to this are kv_impl_t and kv_store_t, which are thread-safe once they are created. However, you should take care to create and release these in a single-threaded manner.

kv_impl_t is created using kv_create_jni_impl() and released using kv_release_impl(). kv_store_t is created using kv_open_store() and released using kv_close_store().
