Ok. I added the tool. I also had to add some cruft to configure.in to
get the --wrap flags in src/testsuite/cyclic/Makefile.

Now, running this test seem to have uncovered a bug with the binary heap
based timers that the latency test did not show. I am investigating on
this, but in the mean time, please do not enable the binary heap timers
option.

Well, thanks. I believe that if the POSIX skin works well, it is simply
because its testsuite has a good coverage. As for the documentation, you
may have noticed that I am in the process of documenting the POSIX API,
you can follow the progression here :

Please, everybody, feel free to send comments, critics, patches.

I guess you would like something like a POSIX API tour, but in order
to write that, we would need a concrete example, such as, for example,
playing .wav files with a PC speaker.
