Because KISS
The design in the OP gives two very disparate jobs to the 'Boss'. It must flip between checking if there are results on the results queue and handling them, then seeing if there is anything to read on <STDIN> and passing it off to workers. The OP is talking about using non blocking calls and sleeps to do this. The complexity clearly recognised by the multiplicity of punctuation marks ... Monitor $RXQUEUE and <STDIN> - simultaneously???
If we split these two functions then we have two simple tasks.
- Listen on <STDIN> and put work on worker queue.
- Listen on results queue and publish results
both tasks can be written with blocking calls ensuring they sleep efficiently until they have work, then spring to work with alacrity when there is something to do.
Cheers,
R.

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).
