What is thrashing? How might it be detected? How might one recover from it once
detected?

Answer:

-Thrashing is the phenomenon that occurs when the total sum of all working set sizes becomes greater than the available physical memory. Productivity drops since the number of instructions that is able to be sent to the CPU drops. It could be detected if a threshold value was put in place for each working set size, and recovery is as simple as suspending processes until total working set size decreases
