Memory leak in Couchbase::Bucket

https://forums.couchbase.com/t/couchbase-bucket-leaks-memory/1932

The following test code:

def loop_bucket_gets
bucket = Couchbase::Bucket.new({:node_list => ['xxx.xxx.xxx.xxx:8091', 'yyy.yyy.yyy.yyy:8091'],
:bucket => 'Foo',
:pool => 'default',
:expires_in => 1.day,
:default_format => :marshal,
:key_prefix => '_foo'
})

i = 0
loop do
begin
i += 1
bucket.get "ABC#

"
rescue ::Couchbase::Error::Base => e
nil
end
end
end

When I execute the method in the rails console, *the memory leaks*.
