Error about recursive nextTick under high load

[ben-ng]

Been noticing this warning while running my front-end test suite. It makes about 50 requests per second and I get a barrage of these errors every 50 or so tests so it's not that readily reproducible...

(node) warning: Recursive process.nextTick detected. This will break in the next version of node. Please use setImmediate for recursive deferral.

Not really sure what to do about it, so I'm hoping it's just a deprecated method being called and an easy fix!

We don't use nextTick anywhere in the Geddy codebase, so it's in a dependency somewhere. Looks like it's used extensively in both async_testing and in mongodb-wrapper. I guess the error means it's getting invoked recursively somewhere. Hope that will help you narrow it -- seems like when you upgrade Node the next time, whatever it is, is going to break.

yup. i'm switching to postgres soon so we'll see if the problem persists.

my hunch is that it's in the ancient mongodb-wrapper version we're forced to use...
