Set the memory usage limit. There are separate limits for compression and decompression (the latter includes also --list), one or both can be set with a single call to this function. Zero indicates resetting the limit back to the defaults. The limit can also be set as a percentage of installed RAM; the percentage must be in the range [1, 100].
