Hmm... Linux+glibc 2.[12] has POSIX aio (an apparent complete
implementation from looking into the aio.h include). But I'm hitting
compile errors:

/ars/squid-src/coss/src/fs/coss/async_io.c:148: undefined reference to
`aio_error'
/ars/squid-src/coss/src/fs/coss/async_io.c:154: undefined reference to
`aio_return'

I see these being exported from aio.h, so I don't know why it's erroring
during the compile.

Interestingly, if I don't enable aufs/pthreads during configure I also
get an error for aio_read--but not when I do. I'm confused, and will
have to tackle this tomorrow, I reckon. I'm guessing aufs does
something that makes aio_read 'findable' but not the other two. Don't
ask me to explain how/why.

Any suggestions? (Henrik, are you standing by somewhere? I guess you
know aio on Linux better than anyone else in this neighbourhood.)
