Patching a sidewall blow out

This morning my nice new thorn resistant tube blew out through the
sidewall just above the bead of bad tire. Upon examination it looks
like just an 1/8 inch tear in the tube. I read some place that
patching a tube after a sidewall blow out is not a good idea since the
surrounding rubber often has undergone extreme stress. There is no
sign of chafing just the small tear from the burst. Anyone have any
luck patching this kind of blow out?
