No, I intend to release new modules to CPAN so we do not have to wait 
for 5.8.1, however, I have said this for 6 months and yet not had the

try it with maintperl and see what happens.

I have got a grant now from TPF that allows me to spend way more time 
on threads again, so I hope to fix the current situation within a
