There's a whole section of the article covering which parts of node may be affected. If the article began by saying it only affects FS and DNS ops, and some drivers, people may be more tempted to stop reading.

Is there any reliable way to check if the libs you're using are subject to this issue?

[spion]

There is a pretty reliable way to make sure they don't: if they don't install any native modules and aren't filesystem or DNS related, they're not affected. If they do, you may grep the native module's source code for uv_queue_work but I don't know if that will catch everything.
