	---- Release V0.21 CPAN ----

	* Temp.pm: Clean out $FILES_CREATED_BY_OBJECT when the destructor
	runs. Otherwise memory does not get returned. Really bad idea for
	daemons. (Thanks to Maxime Therreault RT #37621)

	* Temp.pm: Integrate patches from bleadperl for cygwin. (thanks to
	Jari Aalto RT #36376)

	* t/seekable.t: seekable test was failing on perl 5.6.0 so we now
	skip the specific test. (thanks to Zefram)

	* Temp.pm: Remove the test on the parent directory to see if a file
	can be written. This will be found out anyway as soon as the file open
	is attempted. AFS systems may fail a -w test but still allow a file to
	be created. (thanks to Christopher Ellison)

	* Temp.pm: Put an eval around rmtree. Some versions of rmtree croak
	if you attempt to remove a directory that you are inside. (debian bug
	479317 and RT #35779).

	* Temp.pm: Localize special variables in END blocks and destructors.
