      Description

      QPID-5588 avoids a limitation on the use of file descriptors > 1024 in value by using poll() instead of select() when poll is available. However, the eventlet greenthreads library does not work with poll, only select. Clients that use eventlet greenthreads will fail to operate properly with the qpid python client.

      As the fix to QPID-5588 dynamically chooses either select or poll based on poll's availability, it should be possible to enhance this check to also determine if the select() method has been provided by greenthreads, and, if so, use select() instead of poll(). This would allow greenthreaded clients to work properly.
