JIO_OK ("jump if I/O OK") tests whether CPL ≤ IOPL. The same check gates PUSHF, POPF, INT n, and IRET. The monitor then emulates each instruction as appropriate: maintaining a virtual interrupt flag per V86 task, reflecting software interrupts through the real-mode interrupt vector table, virtualizing I/O accesses, and so on.
For implementers, BYOB adds significant complexity. The stream must track pending BYOB requests, handle partial fills, manage buffer detachment correctly, and coordinate between the BYOB reader and the underlying source. The Web Platform Tests for readable byte streams include dedicated test files just for BYOB edge cases: detached buffers, bad views, response-after-enqueue ordering, and more.
