The 386 solves this by repurposing RPT (Repeat). Normally, RPT implements loops -- it re-executes a micro-instruction while decrementing a counter, as we saw in the multiplication post. But when a protection test is in flight, the hardware suppresses RPT's counter-decrement and turns it into a pure stall: the sequencer freezes until the PLA result arrives.
