Pavel Krajcevski ae2324153d Repurpose the rest of our scaffolding to use Compression Jobs 2013-03-09 13:36:39 -05:00
Pavel Krajcevski 435f935de3 Update atomics compression algorithm 
In general, we want to use this algorithm only with self-contained compression
lists. As such, we've added all of the proper synchronization primitives in
the list object itself. That way, different threads that are working on the
same list will be able to communicate. Ideally, this should eliminate the
number of user-space context switches that happen. Whether or not this is
faster than the other synchronization algorithms that we've tried remains
to be seen...
