    *   (ms) Using semctl to reset the value of the semaphore in the
             Synchronized appender to prevent "Numerical result out of
             range" problem caused by an unbalanced SEM_UNDO when
             incrementing it. Reported by John Little.
    *   (ms) Added parameters in curly braces to cspecs in PatternLayout.
    *   (ms) As explained in  http://rt.cpan.org/Ticket/Display.html?id=41505
             the latest LWP release (5.822) got rid of all of its internal
             debugging functions, making infiltrate_lwp() and its test
             case useless. Disabling it for LWP>=5.822.
