in thread Open pipe to a function?

I can't just redirect it, because I also want to see it at runtime.

    You could probably do some tricks with IO::Multiplex. Just save the orginal filehandle like this:

    my $old_stderr = *STDERR;

    And then reopen STDERR with IO::Multiplex with $old_stderr and a filehandle to the log file.

    How about 
    use IO::Tee;
open(ERRLOG, '>error.txt');
my $tee = new IO::Tee(\*STDOUT, \*ERRLOG);
*STDERR = $tee;
