Yes, I understand, but I think, the scenario of working and always hitting a quota is not normal. I think you shouldn't expect perfect, stable performance etc. in that case. It's similar to if you'll try to work with PG with very little memory and/or shared memory. You can work, but you can easily hit these limits, and than something will not work...
