That's a different problem.

Memory overcommitting means the memory requested to be allocated was of a=20
reasonable size. And when you run out of memory after overcommitting, the=20
application gets a SIGBUS that's really difficult to understand.

What I am suggesting is getting rid of unreasonable memory allocations.=20
There are many cases of backtraces in bugs.kde.org of applications=20
crashing after std::bad_alloc was thrown from the inside of=20
QString::setLength.
