This is not specific to Python. It’s a general limitation of the inotify interface, and is necessary to avoid a trivial denial of service by being slow to consume events. Inotify does tell you when events have been lost, though, which allows you to resynchronize. -- Sincerely, Demi Marie Obenour (she/her/hers)
