From a Solaris 2.5 aio_read() manual page:-
         In Solaris 2.5, these functions always return - 1 and set
         errno to ENOSYS, because this release does not support the
         Asynchronous Input and Output option. It is our intention
         to provide support for these interfaces in future releases.

ie, compiling with Async I/O enabled under Solaris is unlikely to
result in a working cache. I don't think the code tested for this
case (mea culpa) so I'll add a test for this case to the list of
things for the monster patch I keep meaning to send off to Duane which
fixes some of my bugs and makes it compile under IRIX 5.3 etc. Just a
matter of finding the time *sigh*
