Have I miss something ? I found that two features (especialy the first)
are missing in the thread library:

- No way to wait for one thread to finish among many (equivalent of
join, but taking a list of threads as argument)

- No way to send a signal to a thread (it would be useful to make a
thread raise an exception from another thread).

I see clearly a solution with some periodical tests. But this is not
elegant.
