I just noticed a bug in my testbed/benchmarking code. It's fixed, but I decided to compare version 6 of the code against the *unsafe* decompressor again. The results of the three runs I've put it through after changing it to compare against the unsafe decompressor were startling. `Tiny's` compressor is still faster - I've seen it be rated up to 3% faster. The decompressor, OTOH, when compared to the unsafe version (which is the comparison that started me on this binge of hacking), is more than 7% worse. About 11% slower on the original test against a C source file, and about 6% slower for random data. However, looking at the numbers involved, I can't see a reason to keep the unsafe version around - the percentages look worse than they are - from 1 to 3 microseconds. (well, the compressed-cache people might want those extra usecs - but the difference will never be noticeable anywhere outside the kernel)
