Linux copies the sys5 ipc. It works its horrid and maybe the wheel should
have been re-invented to be round instead of square in this case.

The lightweight threads share memory space so I suspect judicious use
of 386/486 properties - notably the exchange register and memory instruction
properties to do spinlocks combined with a signal would work.
