What I would really like to see in asio is asynchronous FS IO (using Ovelapped IO on windows, posix aio where available and a thread pool everywhere else). There have been many requests for this functionality, but Christopher didn't get around to implement it yet.
I have something like that already. But not very well thoughout. On both posix aio and overlapped IO. The biggest problem is that opening a file is *very slow*, and must be done synchronously within a thread pool.
AFAIK there is no posix interface yet for async opens. Don't know about windows though. There is a Linux project to make *any* syscall asynchronous though. Anyways, probably asynchronous open support could be implemented later. Basic AIO would be a first good step.
I think that such a project could be completed in a couple of months. May be the student could even find the time to add pipe support :). As soon as I find some time I'll add the proposal to the wiki.
I want to make a proposal for SoC in boost. But I was thinking about something else (a better bcp utility), I believe boost would benefit from better tools in this moment. Maybe I could apply for both, and boost chooses what (if any) is better for boost.
Go for it! gpd
