+Subject: [PATCH] Zend/tests/bug74093.phpt: Fix failing test case
+
+This test case fails (on non-Windows hosts, where it is enabled) due
+to mismatching output in the error log language. This fixes the
+expectation, and also rewrites the test procedure in a more stable
+fashion.
+
+The objective of the test case is to run a program that exceeds
+the max_execution_time and verify that the process was aborted. The
+previous implementation tested this using a loop on array_intersect with
+large enough inputs to "probably" take enough time to trigger
+max_execution_time to abort it. With faster CPUs, over time this test
+can become flaky. Instead we simply spin a loop until enough
+wall clock time has passed to check our assertion.
