[PATCH] Smarter method caching
------------------------------
Key: JRUBY-1392
URL: http://jira.codehaus.org/browse/JRUBY-1392
Project: JRuby
Issue Type: Improvement
Components: Core Classes/Modules
Environment: rev 4409
Reporter: Alexey Verkhovsky
Attachments: smarter_method_caching.patch
Attached patch makes Petstore under Mongrel-jruby about 10% faster, by doing
the following:
1. RubyModule.includeModule() clear CacheMap and MethodCache selectively,
instead of wholesale.
2. clearing MethodCache resets CacheEntry to all nulls, instead of creating a
new one, which avoids a whole bunch of object instantiations
