I'll leave this question to the gurus, but here is an easy
optimization for your current process. Why not check for the existance
of the tag before you start updating? Ie, branch_foo

# file:
$tag = shift;

@dirs = `find . -type d -maxdepth 1 -mindepth 1 -print`

foreach $dir (@dirs) {
 open(FP, "cvs status -l -v $dir") or die "can't run command: $!";
 while (<FP>) {
  if (/\s$tag\s/) {
     system "cvs update -d -r $tag $dir";
