---------------------------------------------------------------------
We also need to update conf/cassandra-env.ps1 and bin/cassandra.ps1 to keep
Windows' configuration in parity with linux on this ticket; the linked branches
appear to be linux env only.
edit: probably worth mentioning - we don't yet have the performance testing
infrastructure to compare old v. new on Windows w/regards to gc types on the
JVM and interactions w/MemoryManager in the kernel so this would be a "blind"
change on Windows. Given the focus in the JVM on improvements to g1gc I'd
prefer we keep the platforms in parity for now and test platform-specific
nuances w/regards to GC once we have the infrastructure to do so.

> May want to default 2.1 to G1.
> 2.1 is a different animal from 2.0 after moving most of memtables off heap.
> Suspect this will help G1 even more than CMS. (NB this is off by default but
> needs to be part of the test.)
