It seems to work, although it may not have solved my problem:


There are five backed-up pause requests on this server, and it seems
that four of them may be stuck in the xenstore code (apologies for the
lack of debugging symbols on there.  I really ought to get a debug
package built, or haul over an unstripped version of libxenstore.so 3.2
from somewhere).

Information gladly given, but safety requires           Nick Moffitt
avoiding unnecessary conversation.                     nick at zork.net
