Cool :)

There is a typo, tho:

+ /*
+ * If the counterpary is known to have attached, we can read mq_receiver
+ * without acquiring the spinlock and assume it isn't NULL. Otherwise,
+ * more caution is needed.
+ */

s/counterpary/counterparty/;

Sorry, only noticed while re-reading the thread.

Also, either a double space is missing, or one is too many:

+ /*
+ * Separate prior reads of mq_ring from the increment of mq_bytes_read
+ * which follows. Pairs with the full barrier in shm_mq_send_bytes(). We
+ * only need a read barrier here because the increment of mq_bytes_read is
+ * actually a read followed by a dependent write.
+ */

(" Pairs ..." vs. ". We only ...")

Best regards,

Tels
