One other thing I noticed during sync is this: "Adding Swap: 16596k swap-space (priority -3)". When is the swap space deleted? Before or after the reboot of the player program?

The swap isn't deleted as such; there's a 16M partition set aside especially for swap. However, swapping to a spun-down disc is widely regarded as a Bad Thing, so swapping is only enabled during synchronise (in fact, during media checking). Long before the player restart, swapoff() is called.
