22807	Updating a non-expiring transient with a new expiry date does not make it expire	bersbers		"Consider this:
set_transient( 'Bug', 'v1');
set_transient( 'Bug', 'v2', 10 );

The second line will update 'Bug' with 'v2', but will not set autoload to 'no'. Hence, 'Bug' does never expire, and you can get its value 'v2' infinitely using

echo get_transient( 'Bug' );"	defect (bug)	new	normal	Awaiting Review	General	3.4.2	normal
