I don't think this perl is threaded:

Characteristics of this binary (from libperl): 
  Compile-time options: PERL_DONT_CREATE_GVSV PERL_MALLOC_WRAP USE_64_BIT_ALL
                        USE_64_BIT_INT USE_LARGE_FILES USE_PERLIO
  Built under linux
  Compiled at Feb 11 2010 10:52:46
  @INC:
    /usr/lib/perl5/5.10.1/x86_64-linux
    /usr/lib/perl5/5.10.1
    /usr/lib/perl5/site_perl/5.10.1/x86_64-linux
    /usr/lib/perl5/site_perl/5.10.1
    /usr/lib/perl5/site_perl/5.10.0/x86_64-linux
    /usr/lib/perl5/site_perl/5.10.0
    /usr/lib/perl5/site_perl
    .

Could 5.8.9 make a difference or do you just want to make sure my perl is not threaded? I think I'm using some features that are only available in > 5.10.
