I'm not 100% clear on the history here. 5.6 introduces multiplicity and ithreads as experimental, with "no Perl API." In the 5.8 delta, old style threads are called deprecated, and ithreads are touted as a new thing. So it seems to me like in 5.8, the experiment is over and accepted. I will update perlexperiment to reflect this unless someone has evidence to the contrary. -- rjbsThread Next
