Hi WAYNE!

Executables in Linux are demand-paged, meaning only the code that rm really
used at the moment is in RAM. As soon as it jumps somewhere in its code it
hasn't been before, that piece of code (4k at a time) is loaded from disk.
Under memory pressure, code that it isn't running at the moment may also be
discarded.

rm can remove /bin/rm, though, but since the kernel holds a reference to
the file, the disk space is only freed when the rm process exits (this is
necessary in case the kernel needs to demand-page some part of /bin/rm in
before it exits). At first, only the directory entry is removed.
