Thanks for the feedback. I can certainly understand why the blocking techniques are discouraged; it's still hard to get out of that frame of mind!
As for an example of "what I shouldn't be doing", the pull queue API has a lease_task method, but as far as I can tell there is no way to call it and have it block (for any duration) until the first task becomes available. If I try to lease a task via the REST API or the internal API, I ill need to keep calling "lease_task" over and over again until I get some work. So either I burn CPU or I sleep in between calls and I introduce an unwelcome delay in my processing.
