As pointed out by BrowserUK in this node Re: Unix Review column, your:
1 while wait > 0; # avoid zombies
won't work on windows systems. The windows implementation uses the negative of the thread ID as the pid, so wait returns negative numbers for all children.

It seems the most cross-platform wait statement is:
1 while wait != -1 ; # avoid zombies
since the main thread is ID 1, and the child threads won't have that ID. And it's what wait natively returns when there are no further child processes.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • 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).
  • Want more info? How to link or How to display code and escape characters are good places to start.
