Subject: Question for Chess Programmers

Hello,
I have noticed on most all programs that when the program finds a "Mate in 12"
it shows up in the score and the program makes it's move.  The question is:  Why
can't you save the PV and if the opponent makes the next move in the PV then why
can't you continue with the PV without doing another search.  Then continue on
until the opponent is either mated or breaks the original PV.  It seems to me if
you were in time trouble you might lose on time by searching when the moves to
mate are already known.  I guess since none of the programs I know of do this,
there must be a reason for it.  Can someone enlighten me?
