    8.38: How do I timeout a slow event?

    Use the "alarm()" function, probably in conjunction with a signal
    handler, as documented in "Signals" in perlipc and the section on
    "Signals" in the Camel. You may instead use the more flexible
    "Sys::AlarmCall" module available from CPAN.

    The "alarm()" function is not implemented on all versions of Windows.
    Check the documentation for your specific version of Perl.

    The perlfaq-workers, a group of volunteers, maintain the perlfaq. They
    are not necessarily experts in every domain where Perl might show up,
    so please include as much information as possible and relevant in any
    corrections. The perlfaq-workers also don't have access to every
    operating system or platform, so please include relevant details for
    corrections to examples that do not work on particular platforms.
    Working code is greatly appreciated.

    If you'd like to help maintain the perlfaq, see the details in
    perlfaq.pod.
