salva thanks for the suggestion of Proc::Queue. Its simple and very effective.
zentara I'm interested to know about afork() routine. Please walk me through the code. I want to know how the childs are reaped by the parent and how the passed code is executed by the afork() routine
sub afork (\@$&) {
my ($data, $max, $code) = @_;
my $c = 0;
foreach my $data (@$data) {
wait unless ++ $c <= $max;
die "Fork failed: $!\n" unless defined (my $pid = fork);
exit $code -> ($data) unless $pid;
}
1 until -1 == wait;
}

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).

Want more info? How to link
or How to display code and escape characters
are good places to start.
