Not having mysql_close() ... is that a big problem ???

hi gang simple question really (for once): I've written a forum system ... most of it (still lack the edit and perms things, but otherwise it's fully working), over the past 4-5 days ... but I've noticed that on some of the scripts I've forgotten the mysql_close () .... will that cause any protential problems, or should I go through the files and put it in where missing ???? the thing is that it does a few includes criss-crossing a few files ... so finding where to put the damn thing is not always possible, with SQL pulls from 7 tables and such ...
