All the above is true.  My take would be:  py-amqplib is safe to use in 
a threaded program, as long connections (and by extension their 
channels) aren't shared between threads.

py-amqplib does not rely on threading, although the development version 
in the URL above has an optional mode that does use a thread to allow 
some additional capabilities.

I believe that running in the new optional thread-using mode, it could 
still be used in a threaded program subject to the same restrictions as 
the non-thread-using mode.
