Per the File::Tail documentation:
select is intended to enable the programmer to simoultaneously wait for input on normal filehandles and File::Tail filehandles. Of course, you may use it to simply read from more than one File::Tail filehandle at a time.
Your answer makes sense because it doesn't seem to work, but I'd say that documentation is quite misleading. I did find this bug that may be related, but it hasn't been updated in 7 years, so I'm guessing development on this module stopped a long time ago, in a galaxy far, far away...
So for now, I believe the fork/thread methods suggested by aitap and zentara are my next learning adventure...

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).
