    Does this work properly with collect() calls? as in, would the following 
plan still work?
    
    `env = ..
    env.registerCacheFile()
    ...
    someSet.collect()
    <doSomethingThatUsesTheCacheFile>
    env.execute()
    `
    
    if we wipe all cache entries in the collect() call, the files will not be 
registered in the execute(), right? The plans these methods create are separate 
i think.

> When trying to register a file using a constant name an expection is thrown 
> saying the file was already cached.
> This is probably because the same environment is reused, and the cacheFile 
> entries are not cleared between runs.
