This patch adds AIX specific code and I guess the bigger question is 
whether this is the start of a stream of patches to add an AIX port (or 
portions of) to OpenJDK. If so then I think it needs wider discussion. 
The Porters Group (cc'ed) sponsor several porting projects in OpenJDK 
and should be able to advise. If the intention is to get an AIX port 
into OpenJDK then a possible route is to propose an AIX porting project, 
similar to the BSD and MacOX X porting projects.
