OK, this poses the following questions:
- What reasonable limitation can be established on the input, in  
aspect of either quantity or quality? Regarding quality, is safe mode  
enough?
- Is there an option to let LilyPond only render the first page of the  
output, since this web service would only serve the first page as PNG?
- Would putting requests in a queue help? Are there benchmarks on the  
number of acceptable simultaneous requests?
