Caolan McMahon commented on COUCHDB-1075:
-----------------------------------------
Just FYI, this patch makes a fairly normal Kanso (http://kansojs.org) app
respond around 10x faster on the initial request (the one rendered by CouchDB).
Removing the per-request limitation by commenting out the line
"Couch.module_cache = {};" from State.reset you gain another 10x speed increase
on-top of the previous for all subsequent requests.
I think the small risks of users abusing the module_cache for storing state
between requests (which you might argue is at their own risk) are by far
outweighed by the performance increases for serious couchapps.

> Having a CommonJS module A which requires B, when B also requires A causes
> the stack to fill up with require calls. A prerequisite for this fix is the
> caching of modules, even if it is only on a per-request basis.
