Multiple instance detection doesn't work

[kparal]

Detection of second Esmska instance startup through file locking doesn't work anymore.
But it did.

The related code is in PersistenceManager.isFirstInstance().

It seems that file locking now works only inside one Java VM, but not between more
VM instances.

Doesn't work on Fedora 15 and Ubuntu 11.04. Sun Java 1.6.0_26 and OpenJDK 1.6.0_22.

Doesn't concern Windows probably, because we use Launch4J for that there.
