Removing the MMC card will definitely cause Bad Things to happen. It's also very tricky to protect against the Bad Things. The system should listen on the MMC cover events, and turn off swap whenever the MMC cover is opened (which means we have a risk of the card departing). Then the system should hurry to swap in all the pages on the MMC partition, which can take a *long* time depending on the amount of pages on swap. Then, most likely, physical memory would run out. At that point we are in a very bad situation indeed, if pages from some critical system processes are still swapped out. USB Mass Storage is not a problem if the swap resides on a separate partition.
