And, as somebody pointed out to me privately, please note that bug 3774
is similar: http://bugs.squid-cache.org/show_bug.cgi?id=3774

Bug 3774 config is using a single worker, but, technically, it is still
SMP because diskers are kids, just like workers. It may be important
that diskers disappear from mgr:storedir when there is only one worker
because that would kind of match what Kinkie is describing from aufs
point of view (since aufs is not SMP-aware).

HTH,

Alex.
