[OpenAFS] context menu handler slow in OpenAFS 1.5.8 for Windows

Hi,
I'm seeing the exact same thing. Have been for a long time, but
never had proof it was the AFS client causing the right-click delay.
I could send screen shots but its the same behavior already posted
here. I've confirmed it using the pioctl debugging and fs whereis
"my documents" command. I'm using v1.4.1 on a Windows 2003 advanced
terminal server.
Thanks,
- Robbie
