That means that the actual memory used is 235-10-90 = 135MB. The "-/+
buffers/cache" used field gives you the actual amount of memory used
that can't just be thrown away; buffers and cache do not count towards
the minimum amount of memory that needs to be available for everything
to work.

Looks like the high water mark is 174MB, then; although it would be
easier to be sure of that if you'd quoted the number that 'free'
calculates for you. :-)
