Based on this comment I would like to extend the proposed extension

that calling $h->ready() will not waste cycles.

     my $htmp = $h;
     my $coderef = sub { $htmp->ready and push @Readies, $htmp };
     $Callback[$_] = $coderef for @{$h->fileno};

An array ref rather than one number, so handles that have multiple
connections open can report them all.
Yes, this would work. Having each DBD implement their own internal 
select() wouldn't work as well, because two event loops are worse than 
one.
