Volker - can you say anymore about the interface between the VM and 
class libraries? In particular, do you envisage that this project will 
want to evolove the existing interface as part of some future push into 
the main line? I may be reading too much into this but I would think 
that any changes would require wider discussion beyond the porting project.

For the linux-ppc port, and based on your experiences porting to this 
target, do you envisage bug fixes, say for memory ordering issues, in 
many areas of the libraries? If there are non-ppc specific 
reliability/portability fixes then maybe they should be examined on a 
case-by-case basis to see whether they should go into jdk8 anyway, 
irrespective of when the ports come up for review to go into the main line.
