You might be interested in OS memory reclamation with threads on linux. I'm no expert, but it seems that Perl uses some internal calculator, to determine when, and how much memory to free back to the system. It is clearly seen in the above node, where a memory-heavy thread is almost totally released back to the system, but with light-weight threads, it is held onto.
I was musing the other day, that it would be a neat feature to have a "forced demalloc" on threads, where you could specify an option to free all memory used by a thread once it's done, damn the refcount. I would like that option, as it would then be easy to reclaim memory just by putting it in a thread, and specifying "free_all". Possibly warnings may be issued, but another "no warnings:free_all" could be used.

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).
