But you can execute the "mount" command?

If you strace -p on one of these where is it stuck?

I've had luck goining in /proc/{pid#} and using the closefd utility to knock 
processes out of the files they are waiting on.  closefd tells the kernel to 
close a file description, as often a process at state "D" is waiting for an 
event on a description that is defunct.
