Ask Cisco when they cut the Linksys routers' RAM in half a few years ago. Every byte counts. Component cost savings add up when you make a few million of them.

Traditionally yes. On the latest CPUs - who knows.

Of course.

When I wrote that comment I asked myself should I have written "malloc" or "malloc/free" - surely one implies the other.

Fantastic until you need to malloc. You're reimplementing libc, but at least you know what's going on at every level.
