Bug 459944

SUMMARY
Choppy performance when resizing window when ~/.config/yakuakerc is on a slow media (such as rotational), due to repeated calls to syscall fdatasync. (When under very slow media, like an old USB drive, the performance is unbearable.)

STEPS TO REPRODUCE
1. Run yakuake with ~/.config/yakuakerc on rotational medium or other slow medium.
2. Resize the window vertically.

OBSERVED RESULT
While resizing the window vertically, Yakuake process calls fdatasync multiple times, forcing a physical write to the rotational media, making the resizing very choppy.

EXPECTED RESULT
At least it should sync only once, using some kind of debouncing. But ideally not sync at all, since the height of the window is not such an important piece of configuration.
