Upgrade from previous to 9.0.23136 hangs 15% in Removing this previous version

I'm on a macbook pro running 10.9.3 with 8GB of RAM. I turned off my VMs and kicked off the upgrade which i've done dozens of times before. This time the system hangs in Removing the previous version. I don't want to screw things up so need to get it to update properly. What should I do to get the update to run properly? I ran a ps -ef and see a few jobs of interest shown below ...

The lsregister (below) is chewing up 80-84 % of cpu so this is certainly suspect .. What should I do?

davidsmacesktop david$ ps -ef |grep lsreg

Update, after several hours it is slowly upgrading, so it hasn't hung. At this rate it will probably take 24 hours for it to complete the removal process. The lsregister program is now in the 90-95% cpu utilization. the prl_client_app is the only other job that is getting any significant chunk of system resources. I'm inclined to kill -9 the prl_client_app but don't want to risk breaking anything during the removal/upgrade process.

 

Another update. Same thing happened updating again to the version released today. Did more research and problem is lsregister -dump is hanging. I entered "sudo killall lsregister" several times until it killed lsregister, then the removal process continued. There is a root cause behind lsregister -dump hanging that has nothing to do with parallels, investigating now.
