Hi Everyone,

Can I please have a couple of volunteers look over the fix for this CR - 
the webrev can be found at: 

One of the modules in the Kitchensink test generates a VM_PrintThreads 
vm operation. The JVM crashes when it tries to print out G1's concurrent 
marking worker threads when ParallelGCThreads=0 because the work gang 
has not been created. The fix is to add the same check that's used 
elsewhere in G1's concurrent marking.
