+Subject: [PATCH] File::Glob - tweak rt131211.t to be less sensitive on wonky
+ boxes
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+make the test less senstive and avoid divide by zero errors,
+also we skip the test if either elapsed_match or elapsed_fail is
+true, as we can not rely on the timings then. For the operations
+we are doing we should get a non-zero timing from Time::HiRes.
+
+This should mean that running this test on boxes with heavy
+load, etc, will no longer result in false positives.
