Memory was full again yesterday, at which point I tried 3.5.0-rc4.
Unfortunately something there (or something I may have changed in the
config) prevents my google chrome from starting all of my open tabs;
about 1/3 remain blank with a loading spinner running. Opening a new tab
and entering one of those URLs gives "window not responding" error after
some time. Wierd.
