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.

Title:
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.
