    creation.

    Data::UUID::LibUUID will reseed on fork on Mac OSX.

    I have not explored further whether other UUID generators are
    fork/thread safe.

  Benchmarks
    The examples/bench.pl program included with this module does some simple
    benchmarking of UUID generation speeds. Here is the output from my
    desktop system (AMD Phenom II X6 1045T CPU). Note that "v?" is used
    where the choice is left to "libuuid" -- which will result in version 4
    UUIDs on my system.

     Benchmark on Perl v5.14.0 for x86_64-linux with 8 byte integers.

     Key:
       U     => UUID 0.02
       UT    => UUID::Tiny 1.03
       DG    => Data::GUID 0.046
       DU    => Data::UUID 1.217

C<weaken()>, Data::UUID::MT will also reseed its objects on thread creation.
