it is possible to run as many csync2 processes at the same time as you want.
they synchronize using database locks.

the "csync2.lock" file may be created by the administrator, e.g. when one
wants to test experimental config file changes and wants to make sure that
not somebody else is excidently synchronizing them before the tests are
finished.
