No doubt, it should work nice in most desktop usages. But there are some wo= rst -case scenarios like: 1. Working over slow and unreliable media like mounted network shares especially when public networks are used=20 2. Working with userspace filesystems under heavy CPU load and memory press= ure 3. Working with large directories on medium-speed media like USB1/2-dongles I have seen readdir()s lasting for more than minute in real life and it is undesirable to see application stopped that time. I think you can avoid this with using of some async io libraries like libeio but that just moves thread creation from gio to external library. I see more issues in your backend but this one is most important IMO --=20 You are receiving this mail because: You are the assignee for the bug.=
