Squid allocates one shared memory buffer for each cache_dir.

The size of the buffer is SHMBUFS * SHMBUF_BLKSZ. Its then
chopped into SHMBUFS chunks, which are put into the
linked list stack.

If you hit this assertion, it (probably) means there are more
than SHMBUFS I/O's pending. If you get a core dump, you
can print diskd_stats.
