That is, when the trigger pipe is written to, the select/poll/epoll/kqueue wakes up, and can then check the condition variable.  As was suggested earlier, it means an extra 2 fds per thread, but that's much less of an issue since you're not limited to 1024 fds.

I think that's not correct. For C10k you wouldn't start 10k threads, but 
10k coroutines (or simply use the callback interface). AFAIUI one should 
run only a small number of threads to fetch the data from the disk 
(which can't be done asynchronously, at least not with the usual open), 
and one coroutine per connection:
