[IronPython] what does MethodImplOptions.NoOptimization do?

It’s going to disable JIT optimizations on the individual method. This was added because we were seeing some differences between release builds and debug builds around floating point math. We need to track down the real issue but it may just be a CLR bug that doesn’t affect Mono (or maybe it’s a valid optimization that only shows up because floating point numbers aren’t being spilled from their 80-bit internal representation into memory as 64-bit values).

I'm looking at building ironpython on mono to create an rc1 package when the windows one has been released.
in the mathc.cs file on line 383 there is this attribute:
Mono doesn't have that value in the MethodImplOptions there is a work-around. But it did prompt the question what does MethodImplOptions.NoOptimization do?
