Memory leak in LWP is not cured with perl's malloc()

	After having studied other people's reports about memory
	leak in LWP, which I am experiencing myself, I have
	followed the single suggestion I saw from the honored
	author -- recompiled perl with usemyalloc=y -- and alas,
	it is still there.


################
#!/usr/bin/perl -w
use strict;
use HTTP::Response;
use LWP::UserAgent;
use Data::Dumper;

  my $ua = new LWP::UserAgent;
  my $path = 'http://www';
  my $request = new HTTP::Request('GET', $path);
  my $response;

while(1) {
     $response = $ua->request($request);
}

	This program grows in size.  If you substitute
	'http://www' with 'www', making it invalid URI, or with
	'http://nosuchhost', making it not to resolve, it does
	NOT grow.  'ftp://ftphost' grows as well.


	I am using RedHat 6.0 based system, currenty running

	linux 2.2.5 
	perl:
