Automount / Autofs not timing out and unmounting usb flashkey

Hi folks -

Just noticed on two machines tracking the Development branch, that autofs 
seems to be ignoring --timeout.  Eg:

/etc/auto.master:

/misc   /etc/auto.misc --timeout=2

/etc/auto.misc:

usbautocam 
- -fstype=vfat,nosuid,nodev,sync,dirsync,uid=99,gid=99,umask=000 :/dev/sda1


mount shows autofs running:

...
automount(pid6032) on /misc type autofs 
(rw,fd=4,pgrp=6032,minproto=2,maxproto=4)

On device insertion, it is automounted:

...
automount(pid6032) on /misc type autofs 
(rw,fd=4,pgrp=6032,minproto=2,maxproto=4)
/dev/sda1 on /misc/usbautocam type vfat 
(rw,nosuid,nodev,sync,dirsync,uid=99,gid=99,umask=000)


However.... 

[root at fastcat ~]# lsof -n | grep /misc
automount 6032       root    4r      DIR       0,18        0      18246 /misc

Okay so nothing is touching the mountpoint /misc/usbautocam.  Wait several 
seconds and do another mount command to see what is what....

...
automount(pid6032) on /misc type autofs 
(rw,fd=4,pgrp=6032,minproto=2,maxproto=4)
/dev/sda1 on /misc/usbautocam type vfat 
(rw,nosuid,nodev,sync,dirsync,uid=99,gid=99,umask=000)

Previously the mountpoint would disappear after a couple of seconds, now it is 
immortal.

[root at fastcat ~]# rpm -q autofs
autofs-4.1.3-22

Unmounting by hand works okay, and will allow reinsertion of the device, which 
is then automounted again.  But never auto-unmounted.
