UltraRogue: compile out the built-in memory checking. Functions in memory.c tracked and instrumented memory allocation. This mechanism logged information to a text file and also added a 16KB guard area to every allocation. Neither of these are desirable in a multi- user environment, so the whole memory tracking subsystem has been disabled. The behavior can be enabled with a configure flag, but it would be a better idea to use Valgrind to deal with memory bugs.
