I decided to do the nastiest thing I could think of to Cygwin: run a configure script. ;)

In my Windows 10 Technical Preview test VM, Cygwin 64 1.7.33 runs the iperf3 configure script in 20 seconds.  On upgrading to 1.7.34-002, without doing anything to nsswitch.conf, the time remained the same.  On making the suggested change to nsswitch.conf, configure time went *up* to 21 seconds.

So, I moved the new nsswitch.conf back out of the way, relaunched MinTTY, and configure time dropped its extra second.
