It seems like the memory consumption is simply because mod_deflate does
not destroy the buckets it is compressing along the way! David filed
http://nagoya.apache.org/bugzilla/show_bug.cgi?id=29318 on this, I've
added a pointer to a 2.0 patch for this.

The patch works like a charm. The server no longer blinks at the script
being loaded.

Thanks everybody for your help.
