view compilation failing with latest build

[chrisortman]

I am running the tip of http://github.com/loudej/spark

And have been getting sporadic "An assembly with the same simple name
<name varies> has already been imported"

When i check AppDomain.Current.GetAssemblies() sure enough it shows
multiple copies of the same dll, so they are presumably all loaded
into my app domain? Which for the life of me I can't figure out why.

The work is to restart IIS and then clear out the Temporary asp.net
files folder and then it will work again for a little while.

I am running win7 x64 hosting the site in IIS.

I expect I can program around this in the spark code, but I'm more
curious about is this behavior valid and what the heck is asp.net
trying to do here.

Thanks
