Description Adam Stokes 2008-04-16 10:58:24 UTC 
Description of problem:
  "xm dump-core --crash" does not stop guest domain in time.
 In other words, Current RHEL5.2S4 have time between dump-core and destroy.
 It makes guest domain works after core-dump.
 This behavior is not expected one.
 
 From xend.log, domain_id=24 is being destroyed, but unpaused after dump.
