It is not waiting for dossrv to exit,
so much as it is waiting for all the open
file descriptors referring to that window's
/dev/cons to be closed.  Dossrv just happens
to be the one holding them.

The window is reference-counted, and
there are still references.  Try this in a window:

	{sleep 2; echo hello world; sleep 2}& exit

Probably the various dossrv'ing scripts should run

	dossrv </dev/null >/dev/null >[2=1]

but then you do lose any errors from dossrv.
On the other hand, if dossrv does error out
you'd still get an error from mount about #s/dos
not existing, so you would get *some* output.

No, and no.  Well, except for starting dossrv
differently.

I think it has.
