How it works (in short). You may define one or two providers which
gjournal will use. If one provider is given, it will be used for both -
data and journal. If two providers are given, one will be used for data

Every few seconds (you may define how many) journal is terminated and
marked as consistent and gjournal starts to copy data from it to the
data provider. In the same time new data are stored in new journal.
Let's call the moment in which journal is terminated as "journal switch".

server at work. I'd be curious to see how gjournal performs with the
journal on a battery backed ram disk like the gigabyte i-RAM:
