Description:
Got some debug output while shutting down. It doesn't always happen, so repeating it might be a bit tricky (timing issue):

ndb_mgm> Node 4: Node shutdown completed.
bucket == 0, gci:1026 complete: [ GCI: 1027  state: 0x00000000  head: (nil)  tail: (nil) gcp: 0]

How to repeat:

Using: mysql-5.1.7-beta-linux-x86_64-glibc23.tar.gz

Doing in the management node:
  ndb_mgm> 4 stop;

Where 4 should be replaced with an Id which is a data node I guess.

Verified on 5.1.7 (using mysql-5.1.7-beta-linux-x86_64-glibc23.tar.gz)
Had to open bug report, is not always repeatable but should looked into it so debug output never shows in non-debug builds.
