In reference to some mod_cache discussions:
It seems, that after some testing, that in 2.2.3, the core output filters will block when given file buckets, therefore, "stalling" the entire brigade (ie, slowing reads from proxy, cgi, etc.). This was a somewhat artificial test I did, but can someone confirm if something changed in trunk that allows file buckets to be handled differently...
