Parameter read/write in parallel

The (new) unit tests for parameter I/O are failing in parallel (in my
branch) which is not strange considering all processes will try to
read and write the same file.

Any thoughts on how to handle this? There are several options
including include letting only process 0 write and inserting barriers.
