Older versions of the Sys:Syslog module had an interesting feature -
they would crash the calling Perl program if your syslog server was
not running. As of Sys::Syslog-0.15, you can supply an option "nofatal"
when calling openlog(), which will only cause a warning to be emitted
rather than crashing your program.
The workaround above was written before the maintainers of Sys::Syslog
agreed to do anything about the problem - originally when I filed
a bug report they refused to accept it, claiming that it wasn't erroneous
behavior and that to change it now might break someone else's code.
