return early due to signal interruption (EINTR). This makes the
main thread think the async operation is done, but the background
worker thread is still running—risking access to freed memory,
race conditions, crashes or undefined behavior.
Using nxsem_wait_uninterruptible():the main thread waits until the
worker thread finishes, preventing these issues.
