Background

This test application checks for the behavior reported in https://github.com/RIOT-OS/RIOT/issues/100:

Usually, when a thread (here sender_thread) sends a message to another thread (here the main thread) whose message queue already holds a message, the message of sender_thread is copied into main's message queue and sender_thread is set to STATUS_PENDING. However, this should not happen if sender_thread is currently in STATUS_REPLY_BLOCKED mode, since it is in the middle of a different, blocking send.

In the aforementioned issue, it was reported that this undesired behavior was happening. It has been fixed since, and this test ensures that it doesn't re-occur again.

Expected result

The output should look as follows:

sender_thread start
main thread alive

If you see

ERROR: sender_thread should be blocking

something went wrong.
