[ECOS] Seeking Thread join / waitpid equivalent.

[John Carter]

We have just been bitten by the "Don't free the thread into in the 
destructor" problem as discussed so comprehensively by Ivan Horvat in 
April.

Thanks Ivan!

Unfortunately the thread exiting is explicitly our lowest priority 
thread, so Reaper in a mbox trick won't work.

However, in languages such as Ruby, you have the nifty thread.join 
primitive. With processes under posix systems you have waitpid.

Isn't there something like that in ecos, where an arbitrary thread may wait 
for another thread to exit?

The universe is absolutely plastered with the dashed lines exactly one
space long.
