This is a bug report for perl from [EMAIL PROTECTED],
generated with the help of perlbug 1.34 running under perl v5.8.0.
-----------------------------------------------------------------
[Please enter your report here]
Not sure whether this is a bug or a feature:
perl -Mthreads -MPOSIX -e 'threads->new( sub { POSIX::_exit(0) } )->join'
does _not_ exit under Linux. Inspection with "top" reveals that this is
probably caused by the fact that the process for the thread exits without
letting anybody else know it left.
perl -Mthreads -MPOSIX -e 'threads->new( sub { 1 while 1 } )->join'
shows three processes under Linux, whereas the POSIX::_exit() version shows
only two. So the join() is waiting for something that will never come.
So, POSIX::_exit() under Linux is _not_ a good alternative for exiting from
a non-detached thread.
[Please do not change anything below this line]
