<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Calibri","sans-serif";color:black">Honestly I'd sort of think the whole limits.py that is this rate-limiting could also be turned off by default (or a log warn message occurs) when multi-process
nova-api is used since the control for that paste module actually returns the currently enforced limits (and how much remaining) and on repeated calls to different processes those values will actually be different . This adds to the confusion that this rate-limiting
in-memory/process solution creates which does also seem bad.<o:p></o:p></span></p>
