I do not think there is any need to increase the memory usage. Like I mentioned
in the original PR description, even without X running on the same system with
8GB RAM, I could reproduce this using a split command on a 6-7GB file via the
console. 

>> running split on a 6.4G file (filesystem dump of disk using dump) -- something like 
>> split -d -b 200M -a 4 - part 
>> This would then freeze at one point - making the system unusable. I tried this 2-3 times. 

It is very clear there is an issue - and from my experience it is narrowed to
when the ULE scheduler and swapfile is in use.
