Yup. You need to do something that will cause aio_init() to run BEFORE
the fork() runs. In main.c , before the call to ipcache_init(), I
added...

#if USE_ASYNC_IO
    aioClose(dup(0));
#endif

which does nothing, but will force the init to run in aiops. This
stops the problems with the dnsserver stuff. (for the squid-dev ppl:
you end up with 15 threads running on the first dnsserver process. bad
karma). Strictly speaking, it's probably a bug in the linux threads
implementation (it doesn't handle fork as well as it could do), but
the above is an acceptable work around that's harmless on other
systems.
