Cache files not being written

[kbart0]

After upgrading Minecraft to 1.3 and building the newest c10t from source (c87261244a0bf4c05258), cache files aren't being written to disk. I've created a new cache key and the directory is being created, but nothing else.

/x/mc/c10t/c10t -w /x/mc/minecraft-alpha/world -o test.png --cache-dir cache --cache-key oblique -q -m 2 --show-players --ttf-path /usr/local/lib/X11/fonts/webfonts/arial.ttf --ttf-size 30 --ttf-color 0,255,255,0 --debug >> debug.log

Debug output, extra 19000 lines removed.

Hint 1: To use less memory, specify a memory limit with `-M ', if it is reached c10t will swap to disk instead

This is intentional, the new region format needs a cache rework in order to be most effective.

Any update on whether cache will be fixed?
