FSI Shadowcopy -- causes a significant degrade in the fsi first execute time


if you type
there is a perhaps 1 second delay between hitting return and seeing the answer when shadow copy is enabled this delay does not occur when shadow copy is not enabled.
subsequent statements to the first are not delayed significantly.

Per discussion on twitter and internally, this appears to be due to failure of NGENed images to be loaded in the shadow copy appdomain. We need to figure out how to configure the second domain to properly load NGENed images.

I'm having this problem again on F# 4.1. Turning off Shadow Copy makes it start up much faster.
