In the hurdio backend, what would be the appropriate behaviour respective to blocking? I am a bit confused about that because I try to take devio as an example, but D_NOWAIT doesn't work as we would like it to work in Mach. Should the underlying node be opened with O_NONBLOCK? Should read/write operations be performed in that mode as well, and DTR turned on/off along with that? This seems to be what the device code tries to do. Is asynchronous I/O still necessary if we assume proper blocking behaviour by the ioport? Thanks, Marcus -- `Rhubarb is no Egyptian god.'
