/* The MDMA Crew's Proof-of-concept code for the DoS affecting LeafChat
*
* When the LeafChat IRC client recieves invalid data from the server, it
* displays a dialog box with an error message. Should the server rapidly
* send invalid messages, the system soon becomes dangerously low in
* resources and commits harikiri. :-)
