 ===
 * Lock access to the `principal_conn` (i.e. the connection that may be playing) using a read-write lock rather than a mutex. Use read locking when checking that a connection is currently the principal connection before altering any system-wide values such as mDNS flags. This eliminates a number of data race conditions.
