*If* you are using a library of C extensions, and your platform is MRI 
(i.e. the standard ruby 1.8 or 1.9), you may find that when something 
blocks in the C extension then it blocks the whole interpreter.

Sometimes, using a 'pure ruby' version of the library will perform 
better under those circumstances (e.g. there's a pure ruby version of 
the mysql API, as well as the C wrapper one)

But since you haven't posted any code or given any details of your 
platform or what you're trying to talk to, I can't really be more 
specific.

Regards,

Brian.
