It was fam.

I saw this before and traced it with lsof and grep and it was always fam 
holding the mount open.

There seems to be a timing issue, or maybe just a simple timeout going 
on here.  If you try to unmount soon after using a mount, or maybe soon 
after initially inserting a disk (I was using CDs) it will refuse to 
unmount with the error you mentioned.

The more I messed with it, the more persistent it was in refusing to 
unmount, so that's why I think it's a timeout problem.  Time seems to 
fix it most of the time.

Can someone point me to the established practices for reporting bugs? 
What tools should I use to give a standard bug report?

Thanks,

Mike
