This isn't my first rodeo with Hacker News, I've unfortunately had negative responses before when sharing my work.
With your lib and a few hours of work, all that disappeared and CPU went way down. Thanks!
On a side note, users should try to send gratitude to open source authors in general. I know it's hypocritical of me, since I didn't take the time to email you before this! I've done it a few times in the past and the replies I've received indicated that I was the only one to ever thank them! That sucks. I've written some stuff I know more than a few companies built entire products and services with -- I've received about 2 notes in 6-7 years. It's not much but just a bit of thanks really provided motivation.
Cheers to you.
And thanks for saying thanks, it is rare and always very much appreciated.
