+%description threads
+Since Perl 5.8, thread programming has been available using a model called
+interpreter threads  which provides a new Perl interpreter for each thread,
+and, by default, results in no data or state information being shared between
+threads.
+
+(Prior to Perl 5.8, 5005threads was available through the Thread.pm API. This
+threading model has been deprecated, and was removed as of Perl 5.10.0.)
+
+As just mentioned, all variables are, by default, thread local. To use shared
+variables, you need to also load threads::shared.
