with 5c9cc7b7f8920944a413644e1c2ea23bfe655bcb we changed the default
value from ~650 to 4096 kilobyte on 32mb-RAM-devices. This makes them
hardly useable with a lot of oom-crashes. Fix that and keep the default.
For devices with more than 32mb we keep the behaviour and tweak the value.
We dont suppress output of sysctl-command, so the use has a chance to spot it.
While we are at it, localize vars and read the memory without AWK/nonforking.
