Atomic registration: wait_for checks the current value and registers the queue inside the same lock acquisition, closing the race where a transition could slip between registration and the initial check.
In a letter he sent me after his conviction, Friedmann included a poem he’d composed, or, rather, re-composed. It was based on “I Have a Rendezvous with Death,” by the American poet Alan Seeger, who died at the Somme while fighting with the French Foreign Legion. Friedmann renamed it “I Have a Rendezvous with Fate (with gratitude & apologies to Alan Seeger).” He wrote: “Confined in a dark and barren cell / resigned to my own private hell / which nurtures both despair and hate / I have a rendezvous with fate / . . . So that when I draw my final breath / I’ll embrace the soft release of death.”

The tradeoff is complexity. The microcode must be carefully arranged so that the instructions in delay slots are either useful setup for both paths, or at least harmless if the redirect fires. Not every case is as clean as RETF. When a PLA redirect interrupts an LCALL, the return address is already pushed onto the microcode call stack (yes, the 386 has a microcode call stack) -- the redirected code must account for this stale entry. When multiple protection tests overlap, or when a redirect fires during a delay slot of another jump, the control flow becomes hard to reason about. During the FPGA core implementation, protection delay slot interactions were consistently the most difficult bugs to track down.
