Re: Concurrent builds

I've found one possible cause... I was able to stop bind() from failing 
by setting

-Dsun.net.useExclusiveBind=false
as shown on

https://stackoverflow.com/questions/44269863/

however I am no longer able to run the server tests, so I suspect I 
destroyed something in all the mess I added while debugging LOL. (build 
tests did work a week or two ago, so it must be my fault)
