Cassandra does not, since it uses a thread per connection model.  I spent
some time trying to enable it (because I use twisted python) by switching to
the thrift THsHaServer, but this did not work and dropped performance
significantly.  That said, I don't find using a connection pool to be much
trouble, and actually becomes an advantage when you're interacting with
multiple hosts.
