If you really don't want to have the whole list in memory, you'll
have to roll your own glob using readdir. Something like:

opendir HOMES, "/home" or die Can't read /home: $!";
while (my $entry = readdir(HOMES)) {

The first call to readdir() in scalar context will read the entire
list into memory

No it won't.

We have now switched from glob to readdir. Different functions,
different behaviors. (I missed that transition myself at first.)
