OOPS...  mmbackup uses mmapplypolicy.

Unfortunately the script "mmapplypolicy" is a little "too smart".  When 
you use the "-N mynode" parameter it sees that you are referring to just 
the node upon which
you are executing and does not pass the -N argument to the underlying 
tsapolicy command.  (Not my idea, just telling you what's there.)

So right now, to force the parallelized inode scan on a single node, 
please just use the tsapolicy command with -N and -g.  tsapolicy doesn't 
do such smart argument checking,
it is also missing the nodefile, nodeclass, defaultHelperNodes stuff ... 
those are some of the "value add" of the mmapplypolicy script.

If you're running the parallel version and with message level -L 1 you 
will see this message:

[I] 2015-11-10 at 15:57:47.871 Parallel-piped sort and policy evaluation. 5 
files scanned.

Otherwise you will see this message:

[I] 2015-11-10 at 15:49:44.816 Policy evaluation. 5 files scanned.


But ...  if you're running mmapplypolicy under mmbackup... a little more 
hacking is required.
