[Pacemaker] lrmadmin -C blocks on subsequent invocations

[Dave Williams]

OK - I have found you can throw a SIGUSR1 to lrmd to print some debug.
This is the what was shown just after I executed the first 
lrmadmin -C

lrmd doesnt respond to subsequent signal requests so I cannot get any further debug using this technique.
