what is then the proper way to stop a thread blocked on

Oh, this is simple - don't get there... have your code
1. get the FDs associated with IB - which you can retrieve from
librdmacm and from libibverbs
2. make them non blocking
3. add them to you select/poll FD group
4. Use an eventfd or otherwise to break out of the select/poll loop
and then exit your thread.

Thanks, I did not think about eventfd+select.
