in reply to Perl File Handle Count not working as expected, why?

For anyone too lazy to view source on the page, here's his original post with code tags:
#!/perl/me -w use strict; use FileHandle; my $i = 0; # Get the current Process Id my $proc = getpgrp(0); # Create 10 files.. while ($i < 10) { # Get a new File Handle my $fh = new FileHandle(); # Count the File Handle for this process... system ("ls -l /proc/$proc/fd/ | wc -l"); # Open a new File sysopen ($fh, "/tmp/$i", O_RDWR) or die "$!"; # Write something to the file print $fh "stuff \n"; #increment counter, to create a newer file. $i++; ## NO CLOSE... } /tmp> ./perl 5 5 5 5 5 5 5 5 5 5
I was expecting it to go UP by 1 each time in the loop, but it stayed at 5. Why?
