Re: ost::Event and multiple wait()s

[Daniel E Baumann]

OK, yea, the devil is in the details ;). Hmm, alright but with a
Conditional I need to still use a Mutex to prevent the infinite wait
problem right? Which Event takes care of for me. You think it would be
wise to change the signal method of Event to take a boolean to
determine whether someone wants broadcast or not? I sorta of see Event
as encapslating both a condition variable and the atomic (locked with
a mutex) conditional test.

And if cynics ridicule freedom, ridicule community...if ``hard nosed 
realists'' say that profit is the only ideal...just ignore them, and use 
copyleft all the same.
