Ouch, looks like I spoke too soon -- it's happening again without fastcgi in
active use. Here's what the connections in read state chart looks like:

There *could* be a slight lagging correlation with the active connections
chart, showing spikes of connections left in the read state about a minute
after similar spikes in active connections... but it's definitely not a
one-to-one relationship, even excluding the static files being served.
