2230 6295 d 12 h jermar /trunk/uspace/ 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

2229 6295 d 14 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.

This is important for maintaining kernel preemption
since no preemption can take place while a spinlock
is held.
