Subject: Too profiler-happy: with optimization the #7590 actually makes
X-Git-Tag: accepted/trunk/20130322.191538~33718
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=9af0acdbd72c7cf7dd9e593b8f5d51dcf0bfa4f7;p=platform%2Fupstream%2Fperl.git

Too profiler-happy: with optimization the #7590 actually makes
the test to run 0.5% _slower_.  Requires much more instrumentation.
Retract #7590.
