Memory leak when using sample server

[marctrem]

Dear maintainers,

It would seem that, when ran with the --ponynoblock flag, the example http server leaks.

Background: When running into a cycle detector segfault [0] by benchmarking the sample server, @SeanTAllen suggested that cycle detector might me turned off.

With the cycle detector off, when benchmarking, the process just got OOM killed.

I don't think that was a previously mentioned issue so I'm raising!

Thanks,
Marc

@mfelsche can this be closed?

I will verify if this still happens with the new http-server and close it if not.
