    context: Compile Lie with lazy source flag
    
    This flag prevents SpiderMonkey from caching the compiled script.
    Apparently it causes an assertion failure in js::GlobalWorkerThreadState
    on some machines when shutting down JS if the script is cached; perhaps
    because we free the source code string here.
    
    (Unreviewed, but this makes tests pass again on my other machine.)
