What happens to memory after is has been removed from perl (shift/undef/delete etc)?
It is 'put back' into the memory pool perl uses when allocating memory. So when you undef something, the memory that it used becomes available again to be re-allocated.
Can it be reused by other apps?
No, only once the process has exitted will the memory be available to to other apps. This is an OS issue, not a perl issue. See. the recent Memory leak when using hash 'references' for more info on the topic.

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).
