Andrew Reynhout commented on ZOOKEEPER-661:

Looks like emaland forked the old myelin code.  We looked at that, but 
ultimately decided to start over using Ruby FFI.  Also, it doesn't look like 
they've done async calls and watchers yet, but maybe I missed it.

Asynchronous calls were never high priority for my use case, but watchers were 
essential.  Both ran into the same threading problems though, so I ended up 
using the same workarounds.

I've been a bit distracted for the last few weeks, so I haven't made any 
progress on the MT vs ST idea.  I've moved all of the code into a public github 
repo, so if it's useful please check it out.

>             Project: Zookeeper
>          Issue Type: New Feature
>          Components: contrib-bindings
>         Environment: MRI Ruby 1.9
> JRuby 1.4
>            Reporter: Andrew Reynhout
>            Priority: Minor
> Add Ruby bindings to the ZooKeeper distribution.
> Ruby presents special threading difficulties for asynchronous ZK calls (aget, 
> watchers, etc).  It looks like the simplest workaround is to patch the ZK C 
> API.
> Proposed approach will be described in comment.
> Please use this ticket for discussion and suggestions.
