I have a TODO entry saying "instead of triggering the unp_gc task, set a per-thread flag and then do the unp_gc call before returning to userspace; still need unp_gc task for process/thread exit case?" The idea is that if my process closing an fd is responsible for creating unp garbage, it should do the collection and get charged for the kernel time instead of pushing that work to the system.
