There are various bugs with std.concurrency at the moment that make it so that 
it doesn't always work. For instance, I reported this bug on std.concurrency: 
http://d.puremagic.com/issues/show_bug.cgi?id=4601 It relates to threads not 
terminating and/or other threads not running after another thread has run. There  
are, I believe, other similar bugs which have been reported, though I'd have to 
go searching to see what they are.

Personally, I find std.concurrency totally unusable at the moment. It rarely 
works for me, and I just don't trust it. I really _want_ to use it, but it's 
just too buggy right now.
