The canonical example is this:<p>Imagine an installer script that runs a buildscript and then cleans up after itself. So somewhere in the depth of it there is the command <i>rm &#x2F;home&#x2F;gonzales&#x2F;.build&#x2F;foo</i>, but the network connection cut&#x27;s out just after <i>&#x2F;home&#x2F;gonzales</i> so the last thing that the interpreter sees is <i>rm &#x2F;home&#x2F;gonzales</i> and well ... there you go.<p>Stranger things have happened.
