Hi Jeff,

Wait a minute.

Before there was:
#define MPI_MAX_PROCESSOR_NAME 256

Now there is:
#define MPI_MAX_PROCESSOR_NAME OPAL_MAX_PROCESSOR_NAME
with
#define OPAL_MAX_PROCESSOR_NAME 256

Just that now, the user may change it -- the default is still the same.

Where's the break??

We don't

Well -- again, the minimum is a save-guard to not change against something
silly.
And most of the time we will run on systems without specifying the whole FQDN.

Yes, You're right, this is confusing, here the min max key length should be 34
to be on the save side...

Sure, I don't care....

Will do later (it's after 9am EST, so don't wanna change any m4s again...)

Thanks.
