The pernicious USB-stick stall problem

This has become one of my new pet points, queuing theory as it applies to IO has a ton of overlap between Disk IO and Net IO and there should be frequent reminders to make sure that new research and techniques cross pollinate between the two different communities. Storage doesn't have the option to just drop requests and return IO errors like IP does to indicate contention but it can certainly block writers until latencies improve. The same algorithms with different tunables might be useful across subsystems.
