SimilarGallery command fails to return on first use

[twiddli]

The [More like this] view on the gallery page in the web-client will not display similar galleries on first use with a new database. A simple fix is to restart HPX.

Not tested yet but this is likely where it fails to return

happypandax/happypanda/core/commands/gallery_cmd.py

Line 152 in 093ccca

gl_data.update(self._calculate(gallery_or_id, all_gallery_tags).get())

I'm sure the problem lies somewhere in the async module.

Same behavior has also been encountered with the requests module where it'll hang when it's used first thing when the server starts. Really not sure what's triggering it.
Waiting on next gevent release. It might have been fixed.

I think this is fixed in v0.0.14 due to the changes I made on gevent.
