* protect against mem leak in case of failures sending requests to ffi thread * better cleanup if failures in createFFIContext * avoid dangling cstring in handleRes under ARC/ORC * better resource cleanup in destroyFFIContext * invoke onNotResponding if failure in destroyFFIContext * correct seq copy in alloc * make sure the lock is init before cleanUpResources * better possible exception handling in processReq * guard allocSharedSeq if given seq is empty * enhance error handling in ffi_context * add new tests and some corrections
