>             Project: Qpid Proton
>          Issue Type: Bug
>          Components: ruby-binding
>    Affects Versions: 0.8
>            Reporter: Dominic Evans
>            Assignee: Darryl L. Pierce
>            Priority: Minor

> Currently the I/O-style calls to the Cproton methods don't unlock the Ruby GIL, impacting performance as other Threads could be given time on the interpreter whilst the extension code is running. 
> Depending on Ruby version this is simply a matter of wrapping the calls in rb_thread_call_without_gvl (Ruby 2.x +) or rb_thread_blocking_region (Ruby 1.9.x). On Ruby 1.8 I'm not sure if you can enable this, but its my understanding that RHEL requires continued support for 1.8, so some #define work would be needed to perform a no-op on that version.
