And with 5.8.2 on Linux as well.
Oddly enough, this doesn't happen if you do:
foreach 1..6 { my $foo = "perl" x 1000000; sleep 5; }
So, it would seem that Perl doesn't know to reclaim if it is a different scope.
Surprisingly, the following also "loses" memory:
my $foo;
if (1) { $foo = "perl" x 1000000; sleep 5; }
if (1) { $foo = "perl" x 1000000; sleep 5; }
if (1) { $foo = "perl" x 1000000; sleep 5; }
if (1) { $foo = "perl" x 1000000; sleep 5; }
if (1) { $foo = "perl" x 1000000; sleep 5; }
if (1) { $foo = "perl" x 1000000; sleep 5; }
Uses about 28 Mb at the end (the original uses 48 Mb).
Maybe something for 5.8.3 to look at ;-)

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).

or How to display code and escape characters
are good places to start.
