Thats very true. FreeBSD is a little smarter, and actualy kills a runaway
process if it allocates more memory than is available. It of course tries to
page things in and out of swap first, hoping the high memory condition will
soon resolve its self. FreeBSD is also one of the only OSes I've seen that
kick processes (idle ones, i.e., cron, getty, etc) out of memory for kernel
buffers and disk cache to improve preformance for busier ones.
