+About 15 minutes of idle sleeping was removed from running C<make test> due to
+a bug in which the timeout monitor used for tests could not be cancelled once
+the test completes, and the full timeout period elapsed before running the next
+test file.
+
+On a Perl built without psuedo-fork (psuedo-fork builds were not affected by
+this bug), probably since prcess tree kill feature was implemented on Win32,
+killing a process tree with L<perlfunc/kill> and a negative signal, resulted
+in kill inverting the returned value. This ment successfully killing
+1 process tree PID returned 0, and also passing 2 invalid PID, returned 2.
+This has been corrected so the documented behavior for return values for kill
+executes. [perl #121230]
