When you run 9fs, you should be prompted for
a user name and password to use.  Are you being prompted?

try:

   echo hi | 9p write milagro/usr/adriano/ciao

that will cut FUSE out of the loop, just to make things
a little simpler.

Just not implemented.  It should be, it isn't.
You can use this as a workaround:

  srv -a -A main/archive milagro milagro-dump
  9 mount `namespace`/milagro-dump /dump

There is probably some KDE daemon running in the background
that is excited about a new drive being mounted and is scanning it.
("Modern" X window managers like KDE and GNOME just do this
sort of thing, ostensibly to make your life better, though that's
rarely the effect.)  You might try running

  lsof | grep mil/

to find out which programs are holding open references to milagro.
You might also be able use "umount -f" to force an unmount.
