Chemicals from our phone and TV screens are accumulating in the brains of endangered dolphins and porpoises. New research shows these "liquid crystal monomers" from e-waste can cross the blood-brain barrier and may disrupt DNA repair, highlighting the growing impact of electronics on marine life.

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.

To achieve usable performance, every major runtime has resorted to non-standard internal optimizations for Web streams. Node.js, Deno, Bun, and Cloudflare Workers have all developed their own workarounds. This is particularly true for streams wired up to system-level I/O, where much of the machinery is non-observable and can be short-circuited.
