There was a bunch of tests hastily and messly commented out line by line (*whyy?*) ColumnFamilyStoreTest with comments that they are pending SuperColumns support post 8099. Could those responsible please cleanup after themselves? It's been a while since 8099 was committed in the first place

We use posix_fadvise in a bunch of places, and in stereotypical Cassandra fashion no comments were provided. There is a check the OS is Linux (okay, a start) but it turns out the behavior of providing a length of 0 to posix_fadvise changed in some 2.6 kernels. We don't check the kernel version

Hi Kelly- I can't speak to many of your questions as it's not my position to do so. What I can say is that at Apple we are doubling down on open source. We have tons of code in flight -- really big ones in fact -- many already out for review. Our list of enhancements we want to do grows all

I'd like to propose we move from nosetest to pytest for the dtests. It looks like nosetests is basically abandoned, the python community doesn't like it, it hasn't been updated since 2015, and pytest even has nosetests support which would help us greatly during migration
