Hmm, clone() is the basis for kernel-threads, which can be used to
simulate async I/O (and sound like a more modern design), but does Linux
have a direct equivalent of SunOS/Solaris's aioread() and aiowrite() ?
That is, a way to queue a read() or a write() and have the call return
immediately.

According to Sun's manpages these interfaces look like they're
Sun-specific, but some POSIX spec gets mentioned in the manpage for
aio_read (notice the underscore), which isn't "yet implemented on
Solaris".
