It doesn't look like you're handling partial reads

He does. Relevant code:

while(my @ready = $select->can_read) {
...
      my $data;
      my $length = sysread $fh, $data, 4096;

...
           $processeddata .= $data;
...
}

All the data ends up in processeddata, no matter how much is read by a given call to sysread.

It doesn't look like you're handling ... other exceptional conditions

He does this too. Relevant code:

      if( ! defined $length || $length == 0 ) {
        $err .= "Error from child: $!\n" unless defined $length;
        $select->remove($fh);
      }

The filehandle is removed from the list of handles monitored by select. I'm guessing can_read will return false when it no longer monitors any handles.

Something like this might be a start.

That's bad! You removed select, which is cruicial here.
