When detaching contexts, we may still have interrupts in the system which are yet to be delivered to any CPU and be acked in the PSL. This can result in a subsequent unrelated process getting an spurious IRQ or an interrupt for a non-existent context. This polls the PSL to ensure that the PSL is clear of IRQs for the detached context, before removing the context from the idr.
