3-post thread. Replaces the mmap fixed-size log file with a CART file
mmapped on CPU with mapped GPU access (no file IO) + background page
walker to prevent paging out. Beginning of CART is a grid of 32-bit
unsigned values, hex-dumped as the 'log file' to either term or GPU
render. Same framework for CPU and GPU debug ('write and it just
appears'). Visualized as 4-bit/char hex terminal with hex font.
