I'm having exactly this problem using Elixir/Pylons/Mysql. Repeatedly
reloading a web page, debug-level sqlalchemy output shows the sql
query going out, and the correct (time-varying) data coming back, but
about 1/3 of the time a stale page is ultimately displayed on my
browser instead of the updated value. Have not traced this through the
templater and out the web server yet, would love to hear someone
else's success there.
