proxy and fastcgi, both of which appeared to be working fine. Weirdly, on my
WordPress hosts I was correctly receiving the page (PHP via fastcgi), but
not some of the static files, so it would just sit there waiting for ages...
perhaps keepalive requests were failing?

Static files on other hosts were working (one static html file delivered by
nginx + a bunch of generated images behind the nginx proxy -- collectd).

Build differences between my 0.8.10 and packages -> added the geoip
and static_gzip modules.

(For now, I've switched back to 0.8.10, but can do more testing with if required.)
