This and some other recent minor modifications are included in
(generated from today's CVS HEAD).

* When activating an LV, remove any stray LVM1 /dev nodes and group file.
* Also lock memory during LV updates.
* When there are device name aliases, choose the "nicest" to display.
* Correct error message for non-snapshot activation failure.
* More docn for filter changes.
* Ignore filter cache at startup if config file is newer than cache.
* Detect duplicate PV uuids with new metadata format - select the one 
  on an md device if appropriate.
* Default stripesize 64k & config file setting for it
* Clear many compiler warnings (i386) & associated bugs - hopefully
  without introducing too many new bugs:-)
* Default compilation has optimisation - or else use ./configure
