You should get minimal backtracking. At the start of each word in the comment it will backtrack over the space between words.

You should look into building your own up-to-date perl. I've found it to be remarkably easy on both Solaris & Linux boxes, and you get to use the latest & greatest perl for you own work. Just leave the system version where it is, and put your own on the #! line of your programs or put it earlier in your personal PATH.
