Gentle monks,

Does the :locked attribute not work under 5.8.0? For example, I expected the following

  $ perl -Mthreads -le \
  > 'sub f :locked {print $_[0]; sleep 2; print $_[0];}
  > threads->create(\&f, $_) for @ARGV;
  > $_->join() for threads->list()' foo bar

[download]

always to print "foo\nfoo\nbar\nbar\n", just as if I'd manually lock()ed a shared variable at the start of the sub. Instead, the f() calls run on top of each other. (e.g. - foo bar foo bar)

This happens both with redhat's perl-5.8.0-55 and with perl-5.8.1-RC5 on linux 2.4 -- and, yes, $Config{useithreads} eq "define" :)
