Since we have less than 100k of usage.h data anyway, using bzip -9 is silly.
That says use 900k chunks when compressing, which needs about 4 megs of data structures to undo the Burrows-Wheeler transform. Switching it down to bzip -1 (100k chunks) should have no impact on the compression (since it still all fits in one chunk) but should reduce runtime decompression memory requirements to something like 500k. Still larger than gunzip, but not egregiously so.
