Description Andreas Kling 2014-03-07 13:35:56 PST 
After fixing the leak in r165252, I was surprised to find that it didn't
show up on memory test bots. It turns out that while the memory is now
getting freed, the system malloc implementation doesn't actually release
pages back to the OS until there is memory pressure.

Since we are just faking the memory pressure on bots, we have to let
system malloc in on the fun, so we can get representative numbers.
With this change, we should finally see the effect of not leaking the
URLRequest object tree.
