I actually submitted a bug report because noprocrast stopped working properly for me, so it became pretty much unusable to actually go on hackernews for more than the allowed time and post comments, which is really more in the spirit of noprocrast... but incredibly frustrating.

It took years (weeks) to fix. I disabled noprocrast in the mean time. (I guess I should turn it back on now)

If you use this feature and you noticed the bug, thank @kogir I guess!
