You must not add & at the end of the globus-credential-delegate command, because the job submission commands require the delegation command to have finished. Otherwise there won't be an epr of a delegated credential.
Ok, I think what I get out of this is: It works sequentially (that is what I wanted to confirm, so the usage of the commands is ok), but maybe not using pthreads. I don't know what the problem might be. Maybe Joe Bester who wrote the command-line tools can provide more input on this.
