SSE is Streaming SIMD (Single Instruction Multiple Data) Extensions; which 
means processing more than one thing at a time, as simply as I understand 
it.

I checked that focalblur.pov and the same thing happened here. Stopping the 
render doesn't stop POV from using 99% of the CPU and when it finally closes 
it pops up a box with the following:
-------------------------------------------------------------------
Microsoft Visual C++ Runtime Library

Runtime Error!

Program: Program Files\POV-Ray for Windows v3.6\bin\pvengine*.exe

This application has requested the Runtime to terminate it in an unusual 
way.
Please contact the application's support team for more information.

* happens with both the 3.7 beta 7 or the sse2.
