The problem is that I had around 100 tabs and xulrunner-6.0 was using
roughly 1-1.5GB VIRT memory, so is 1.5GB the upper limit?

xulrunner-7.0 seems to use the same amount, let me see if it will be
killed someday:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND
 2886 luca      20   0 1147m 727m  24m S   10 36.3   3:27.64 xulrunner-bin

Two things I have completely forgot to add while reporting the bug:

a) no external plugins here (no Flash/Gnash, no Java)

b) xulrunner is the main battery drainer (see the CPU/MEM consumption
   above), which is a bad effect other than the hibernation one already
   reported, here the powertop output for the same session above:

         Usage       Events/s    Category       Description
     132.1 ms/s     373.4        Process        /usr/lib/xulrunner-7.0/xulrunner-bin

Thx, bye,
Gismo / Luca

PS, I do not want to leave xulrunner/conkeror, so please do not tell me
    that no one upstream cares about that ;-)
