Subject: Cache KEYWORDS and EAPI metadata values in order to speed up portdbapi.gvisible(... 
X-Git-Tag: v2.1.2~294
X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=25ded51d2804109347a3a6fa96ef44e4a7833df0;p=portage.git

Cache KEYWORDS and EAPI metadata values in order to speed up portdbapi.gvisible() calls.  This greatly improves repoman performance (help emerge a little too).
