Use the iterator with a while loop and just keep a count (or array) of the number of randomly selected files. Use last when you have enough. Or, if you run out of files, re-generate the iterator.

For what it's worth, you can even put the randomness into the iterator:

my $rule = Path::Iterator::Rule->new->file->and(sub { rand() < 0.1 });

I just shipped PIR 1.005 to CPAN to fix broken tests on Windows.
