Bad behavior is device dependent with only network based USRP devices affected. USB based device thread behavior stops and shutdowns as expected. Tested with N200, X300, and B210. Tested solutions include the following: 1. Set pthread_setcanceltype() with PTHREAD_CANCEL_ASYNCHRONOUS 2. Add sleep delay to allow I/O threads to timeout before stopping the device 3. Wait for I/O threads to join after cancellation before stopping the device This patch resolves the issue by with the third approach. Number 1 is not guaranteed to always work with UHD internals as driver code may explicitly set thread parameters. Using sleep calls to fix order-of-operation issues is almost never a good idea.
