The stat theory is very interesting, but it is unclear to me if it explains all of the problem.

I setup a quadruple boot x86_64 machine with 4GB of ram and 4 cores:
Winxp 32bit
Win7 64bit
Solaris 64bit
Ubuntu 64bit

And tested the build times on the different OS:es.

Ubuntu Fastest by far.

Solaris, slower, but this is only because of bad CC performance.

Winxp, even slower but still ok.

Win7, ridiculously slow. The configure script prints one line per second!

Clearly, just running a bash script in cygwin/win7/64bit is problematic.
If we get 10% speedup from dash, then that is not going to help because
the slowdown is a factor 10.

Could someone try out the difference between a 32bit win7 clean install and a 64 bit win7 clean install when running the latest cygwin and just the build-infra/jdk8/common/autoconf/configure script?

(My patience for installing many OSes into the same box, just ran out. And virtualization
testing can give a hint, but cannot be entirely trusted.)
