Sorry again, I thought it was clear when I said "sorry" first time I admit this fact.
Thank you for reprimand.

Feature #5427: Not complex patch to improve `require` time (load.c)
http://redmine.ruby-lang.org/issues/5427
Author: Yura Sokolov
Status: Open
Priority: Normal
Assignee:
Category:
Target version:
Currently `loaded_features` are unsorted, so that `rb_feature_p` ought to iterate over all `loaded_features` to figure: is requested feature loaded?
After this patch `loaded_features` is kept sorted by basename without extension (/usr/lib/ruby/asdf.rb => asdf). When `rb_feature_p` start its check, it goes straight to the first item with matching basename (using binary search) and stops after last.
Methods `$LOADED_FEATURES.<<` and `$LOADED_FEATURES.push` are overriden to keep sort order. `push` accepts only 1 parameter, but it seems that no one pass more to it.
Currently I choose to consider characters of basename in right to left order, but it could be changed, I think.
