It's a shame that you didn't report it, because I was unaware of this until 
now.

Anyway, I'm unable to reproduce this bug (purging files from cache after 
restarting nginx works as expected, at least with nginx-0.8.8, so maybe you 
introduced some bugs while syncing it on your own?)

Also, the message you are referring to ("cache file \"%s\" is too small") is 
produced by nginx when it's trying to open cached file (which is also done 
before purging it), so it looks like something is wrong... It would be great 
if you could produce debug log and send it either on- or off-list.

Actually, I was going to sync it with the latest nginx and push the release 
yesterday, together with ngx_supervisord-1.1, but something came up and I 
didn't do it...

But I'm gonna do it in next few days (maybe even today), stay tuned! ;)
