There could be one instance of the checkpoint active at the time but
that is only because the TST_CHECKPOINT_INIT() does not take the FIFO
name as a parameter. The rest of the code does mostly what the pipe()
does but includes the timeout detection and has more strict error
condition checks.

If you create one checkpoint at global setup, you can reuse it in the
rest of the testcases given that WAIT and SIGNAL is called exacly once
for each test and test are not executed in parallel.
