-Every 5 seconds, gargoyle will pop up an empty message box then unmark itself executable. For fun, use [Sysinternals's excellent VMMap tool](https://technet.microsoft.com/en-us/sysinternals/vmmap.aspx) to examine when *gargoyle*'s PIC is executable. If a message box is active, *gargoyle* will be executable. If it is not, *gargoyle* should not be executable. The PIC's address is printed to `stdout` just before the harness calls into the PIC.
