Can't start X twice in the same Hurd session

[David Coquil <dcoquil@lisi.insa-lyon.fr>]

	Hi all,

If I startx once, then exit X, either by killing the server with
Ctrl-Alt-Backspace or using the "exit" function of the window manager, then
X won't start anymore. I get the following output :

_XSERVTransSocketINETCreateListener: ...SocketCreateListener() failed
_XSERVTransMakeAllCOTSServerListeners: server already running

Fatal server error:
Cannot establish any listening sockets - Make sure an X server isn't already
running

When reporting a problem related to a server crash, please send
the full server output, not just the last messages

_X11TransSocketUNIXConnect: Can't connect: errno = 1073741826
_X11TransSocketUNIXConnect: Can't connect: errno = 1073741826
_X11TransSocketUNIXConnect: Can't connect: errno = 1073741826
_X11TransSocketUNIXConnect: Can't connect: errno = 1073741826
_X11TransSocketUNIXConnect: Can't connect: errno = 1073741826
_X11TransSocketUNIXConnect: Can't connect: errno = 1073741826
giving up.
xinit:  No such file or directory (errno 1073741826):  unable to connect to
X server
xinit:  No such process (errno 1073741827):  Server error.

I use the 3.3.6 X packages.

This happens regardless with any window manager. ps does not report any
running X related process.
Seems like some 'ressource' is still locked after X exits. Any ideas ?
