You need to specify "arg_gtio.o" with the transfer_output_files parameter
in your submit description file. In most universes in Condor, if you omit
transfer_output_files, Condor automatically transfers back all
created/modified files in the job's execute directory. This doesn't work
in the globus universe, as Globus doesn't an appropriate mechanism.

I see that this exception isn't well documented in the Condor manual. I'll
see that we fix it.
