No doubt, it should work nice in most desktop usages. But there are some worst
-case scenarios like:
1. Working over slow and unreliable media like mounted network shares
especially when public networks are used 
2. Working with userspace filesystems under heavy CPU load and memory pressure
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
