We are currently investigating why https://yellowgrass.org/issue/MetaC/33 results in a blank page.

We already increased markdown parse timeout and return appropriate error message, but for some reason this code isn’t touched in this case.

Definitely caused by pegdown issue #43: Extremely slow parsing for certain pathological input
I replaced the underscores in problematic text and no timeouts anymore.

Now using a patched pegdown lib.
