Yeh, it's a bummer. For years a buddy of mine said that this and asynch
I/O was sorely needed in UNIX, but only in the past few years did I come
around. You should be able to do a poll/select on *any* file descriptor
or combination thereof. Not only that, but you should be able to post
a read() without waiting. This would be a much cleaner technique than
either select() or poll(), and would allow all sorts of nice epiphenomena.
For example, you could explictly read-ahead on a raw device...
