  Windows console anecdotal slowness

I upgraded my renderfarm from 3.7.1-alpha to 3.7.1-beta.3
and I'm seeing some odd rendertimes.

( http://www.buckosoft.com/bsac/meta/
click on the "Servers" tab)

Often, my 8-thread windows i7 runs almost twice as fast as my 4-core 
Linux i5.  Minimally, it is about 20% faster.  (The Total FPH column)

But with this build, I'm seeing an extreme slowdown with the Windows 
console version.  It is running at half the speed of my i5!. (The Cur 
FPH column).

These numbers can only be viewed as relative to each other.
Also interestingly, my Ubuntu 16 box is "faster" than its average while 
my other 3 Ubuntu 14 boxes are "slower" than their average.  I would 
expect them to all weight the same against their average.

After this job is done (adding BorderChars to the credits of my 
animation) I will go back and run some timed tests on the different 
versions.

The Windows box *is* running flat out, pegging my CPU, with 
povconsole64.exe averaging 95.96% of total CPU time of my system. 
(Watching the Super Bowl ate some CPU ;) )
