(In reply to comment #3)
> Why marking this as blocking asynchronous I/O?
Well, no hard dependency. I just thought it would make sense to do this first,
as it would reduce the work required to convert the library to a more
traditional read/write design. I'm sure it's possible to shoehorn async i/o
into the current library as well. Especially as there is no point in adding
support for "real" async i/o at the moment, since e.g. Linux supports it only
in conjunction with direct I/O. Frontend syntax support can be added before the
actual backend takes advantage of it.
