Description of problem:
cluster_test (part of make check when cluster configured using openais service) sometimes dumps the valgring memory leak.

Version-Release number of selected component (if applicable):
tested on revisions 721111 and 720809

How reproducible:
40-60%

Steps to Reproduce:
0. install openais-devel openais and setup openais.conf
1. service openais start
2. check-out the qpid source tree
3. cd qpid.../cpp && ./bootstrap && make && make check
4. check the logfile / transcript
  
Actual results:
Running 12 test cases...
