Copying large files via CIFS mount over slow network causes lockups
I encountered multiple lockups (several minutes long) where all Thunar windows refuse to respond, when copying a few large files (approx 2GB each) via CIFS (using mount.cifs). It always recovers eventually, and usually around halfway through the transfer. It's over a 2.4GHz WiFi link which results in speeds of around 65Mbits/s (8MB/s). This doesn't happen with other file managers like PCManFM. I'm using Thunar 4.16.8 on Linux Mint 20.3 Xfce.
