-# Many tests wait for an actor to call a mock method.  They poll very
-# regularly (see wait_for_call in ActorTestMixin), but if you've
-# broken something, a long timeout can mean you'll spend a lot of time
-# watching failures come in.  You can set the ANMTEST_TIMEOUT
-# environment variable to arrange a shorter timeout while you're doing
-# regular development.
+# Set the ANMTEST_TIMEOUT environment variable to the maximum amount of time to
+# wait for tested actors to respond to important messages.  The default value
+# is very conservative, because a small value may produce false negatives on
+# slower systems.  If you're debugging a known timeout issue, however, you may
+# want to set this lower to speed up tests.
