I tried e-cli-addon-docs but found that my ember serve stalled on the first attempt to recompile the app after changing a markdown file (or any file really), and it only started happening after adding e-cli-addon-docs.

Here's what I see

It never successfully recompiles after this point, attempting to reload the browser just spins indefinitely.

Here's the branch of ember-constraint-router that demonstrated this. To reproduce, run ember s, let it compile once, then change one of the .md files in the tests/dummy/app folder.
