I did a ktrace on mt and discovered that the driver was NOT
returning an error on the fsf IOCTL. It looks like a driver
problem. I've been looking at the sources, but the EOM logic
escapes me. Has anyone else played with/patched this code?
I know the logic is complex due to asychronous IO and early 
returns. But I can't see the forest for the trees.
