I discussed it with our developers.

There is several problems if launch JVM directly from PowerDNS
1. multiple independent JVM processes consume much more memory
2. our application checks the status of the remote servers. So, when run 
multiple instances the number of tests increases respectively and/or we 
need to synchronize instances with each other. This complicates the program
3. currently we use the JVM stdout for logging. it is convenient and 
work for all our applications

I could probably think of some more examples of why we would like to use 
a single JVM application per server and unix socket for communication 
with PowerDNS :)
