no it does not CRASH
but it starts crawling around because the system starts
to swap and i have never seen any linux system not
get unuseable for my taste while heavily swapping
what is so difficulty to undersatnd:
a application has the choice:
* holding data in memory
* writing data to a file
if the application thinks the data of the current workload
is too big for memory why would it be a godd design for a
operating system-default to say "does not bother me"?
