I started to write a post saying "ok - can't start a new thread - so how can I run a background task?" and then I really struggled to find an example that couldn't be solved some other way.
The only example I came up with was a major processing task, maybe some major calculation or db search/analysis, that is kicked off by a request, runs in background and sets an indicator when completed. 1) what other background tasks do people envisage? 2) how should you do it in web2py?
