Thanks for looking at it. We can't break out of the loop. This is part 
of the asynchronous close. N threads are doing I/O on the file. We use 
our dup2 trick to close the file and signal the threads so that complete 
the I/O operations quickly. This loop is just waiting until all the I/O 
operations have been completed so that the close can continue and 
release the file descriptor.
