Memory Leak in pthread_create

[pasetti]

The test cases in CrFwSocketTestCase create threads with pthread_create but do not join with them before terminating. This may give rise to memory leaks which are detected by Valgrind.

If I wanted to avoid them, I should:

• Make the threads accessible outside the modules where they are created (e.g. OutStreamSocket)
• Perform pthread_join in the test cases where the threads are created
