:I'm not so sure - essentially softupdates updates in memory and drags its
:feet a lot before writing to the actual disk. A swap file on the other

:memory usage, thereby increasing the swap file utilization - a vicious
:circle.

I don't think it makes a big difference memory-wise, because the system
tends to try to cache the data for a period of time anyway.
