Sync and display process names before umount. (#116)

* Test ignoring copy fail.

* Sync before unmounting.

* Sync before each unmount.

* Print running processes before umounting everything.

* Fix ps all

* Make sure that all the qemu processes dead before umount.

* Force kill processes and unmount.

* "Graceful" force exit.

* Nice print for killing processes.
