very high is relative

and it did not abort with a out-of-memory on a 64 MB device and so 
finished - what to complain then - memory is there to be used and 64 MB 
in 2017 i would not expect to run anything which does really some work

there are even not much systems booting with 64 MB todays when every 
clock has 1 GB or more

if there would be memory leaks you would end with OOM very large on such 
a device
