This looks really useful.

In the coming weeks i will try and use it in one of the apps i am building on tornado.

Kudos to Greplin.

Just one question. I see Tornado related repos in Greplin Github account. Are you using it in one of your Tornado apps ? In that case any gotchas regarding blocking ?

We do use it in Tornado apps. We haven't seen any blocking issues so far as the time to write the tiny file is pretty small plus this happens on a small percentage of requests. It'd probably be worth looking in to an asynchronous model at some point though.
