[web-devel] Quitting Yesod

[Aur Saraf]

Hi,

Your method doesn't work for me. I tried it with a page that doesn't
consume all RAM.


I get an empty prof file. It is dated correctly.


I'm retrying with explicitly setting -auto-all and -caf-all in cabal.
Perhaps it was not the default.


I'm testing with `links` (since I'm working over SSH tonigh).
