Hello Sam,

  tried with CS trunk r38578 built in debug mode on a Core2-Duo T6400 2GHz
64bits Linux.
With CEL r4933 : construction takes ~4s
With CEL r4936 : construction takes ~3s
FPS were about the same in each case. I didn't notice notice functionality
differences.
I'll retry with optimized builds later...
