I confirm that the VmData of konsole does not decrease when closing a tab with
a huge history, so there has to be a leak.
And I made a small malloc/free testcase to double-check my measurement tool:
indeed, when free() is called, VmData and VMRSS decrease accordingly.

I don't know konsole enough to debug this, but I used gdb a bit and I do see a
lot of destructors being called when closing tab: ~Screen and especially
~HistoryScrollBuffer which deletes _historyBuffer (and that took a really long
time, so surely that was big). And yet VmData didn't change at all. Puzzling.
