Description Antonio Garcia-Dominguez CLA 2011-06-06 16:26:04 EDT 
Due to the way Eugenia waits for a file to be produced, sometimes it keeps on waiting forever for a file. It's not too noticeable in a single-core or dual-core computer, but it seems to be more frequent in quad-core machines.

Normally, Eugenia starts the transformation to generate the models, refreshes the models and then waits for the file indefinitely. I think it would be safer to start generating the models and then refresh and check if the file exists repeatedly, with a slight delay between checks to avoid hogging the CPU.
