Message:

Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:

• there _must_ be a futex to serialize access to printf()
• there _must_ be pseudo thread serialization in printf()
• the best place for this is vprintf(), the one that goes to console
