its just a matter of the size of the overall memory one system has
until it breaks down.
i.e. whether there are 8GB ram or 4GB ram and 4GB swap doesnt change
anything. when the 8GB are eaten up, its over.
besides with ram-only, there is no slow down caused by swapping
until the death.

additionally, if there is plenty of ram, there should be no reason
for i/o cache data to kick program data into the swap area.
just because big files are being copied doesnt mean it is acceptable
for gui’s to be slowed down after the file operation is done.
