Test failures with dalli 2.3.0

[graaff]

I'm getting a number of test failures with dalli 2.3.0. As far as I can tell these are due to my system not running a default memcached instance. An excerpt of the errors is below. In total I get

85 tests, 13422 assertions, 0 failures, 14 errors, 4 skips

I'm trying to get these test in shape for Gentoo, so that we can update our package of dalli. In Gentoo we offer users the option to run tests when installing a package, but in that case I can't make the assumption that a default memcached instance is available, and due to permissions I can't start a default server. It looks like most of the other tests are working around this by starting their own instance of memcached, and that's fine. I wonder if that can be done here as well.

Hope this is not too OT, but if you make this available in Gentoo, would you consider trying to make the 1.1.x available as a slotted version as well? (2.x doesn't do unix domain sockets, among other differences)

Removing stuff is always my favorite way to fix bugs :-) Confirmed that this is all fixed for me with dalli 2.5.0.
