What I wrote yesterday was correct but incomplete.
In addition to the file descriptors, dossrv is holding
up a reference to the window's name space, in which
the window files are still accessible. If you do
slay dossrv |rc # clean slate
unmount /mnt/wsys /dev
unmount /mnt/wsys
9fat:
exit
then the window does in fact disappear.
