ignore .so libraries in the lib dir
WIP - got basic O_DIRECT support working (with aio), but it fails on compressed files
due to the extra 4 bytes after the compressed block. O_DIRECT wants to read the entire chunk
(based on buffer size, which *must* be block-aligned (512)), and we're not ready for having a cache
layer for reads which then 'deserializers' (like RAR/CRAR) pull from
