Is it possible to receive a message without having specified a source in
pypar, but with just specifying e.g. a tag? This would come in handy when
a master node distributes jobs and waits for results, to send out a new
job each time a slave is done. The master would like to first receive the
results from the first slave who finishes his job, but we cannot know
beforehand which slave that will be.
