Known bugs

Are there any known bugs or limitations?

Yes, there are, and here's an example. Let's assume you check how much memory 'postgres' uses. This can be done by executing:
echo "q" | top -b | grep "postgres" | awk -F " " '{ memory += $10 } END { print memory }
Let's assume the numbers were: 0.2, 3.6, 3.5, 0.1, 0.0, 0.0, 3.7, 1.0, 0.6, 0.4, 2.4, 2.5, 2.3, 2.5, 0.4, and 0.4. The output number is 23.6, and it's a valid percentage value. Here's a Perl 1 program generated with the Awk to Perl translator from the 'x2p' subdirectory. It's a slightly modified version of it.

#!./perl
eval '$'.$1.'$2;' while $ARGV[0] =~ /^([A-Za-z_]+=)(.*)/ && shift;
                        # process any FOO=bar switches

$, = ' ';               # set output field separator
$\ = "\n";              # set output record separator

while (<>) {
    ($Fld1,$Fld2,$Fld3,$Fld4,$Fld5,$Fld6,$Fld7,$Fld8,$Fld9,$Fld10) = split(' ');
    $memory += $Fld10;
}

print $memory;

The output number is now 23.599999999999997868, and that is a slightly different result. The difference is 0.000000000000002132.
