win7 jdk 8 build : fork: retry: Resource temporarily unavailable

[Erik Joelsson]

"fork: retry: Resource temporarily unavailable" is a classic cygwin 
problem. I don't think it's related to amount of memory used. One thing 
you can try is rebaseall described here: 
http://cygwin.wikia.com/wiki/Rebaseall. It sometimes helps.
