fair pushback, though s/unless they're also modifying the page table/unless they're also accessing the page table/, as it too needs to be synchronized. so yes, sometimes it has no effect, but given how often programs end up loading, crosstalk is super common
Crosstalk is absolutely common for a number of operations, but that crosstalk is NOT the same as blocking until the page is loaded into RAM. That operation is blocking on IO.
