=head1 NAME

threads - Perl extension allowing use of interpreter based threads from perl

=head1 SYNOPSIS

use threads;

sub start_thread {
    print "Thread started\n";
}

my $thread = threads->new("start_thread","argument");

$thread->new(sub { print "I am a thread"},"argument");

$thread->join();

$thread->detach();

$thread = threads->self();

threads->tid();
threads->self->tid();

$thread->tid();

=head1 DESCRIPTION

Perl 5.6 introduced something called interpreter threads. Interpreter
threads are different from 5005 threads by creating a new perl
interpreter per thread and not sharing any data or state between threads.

Prior to perl 5.8 this has only been available to people embedding perl and
for emulating fork() on windows.

The threads API is loosly based on the old Thread.pm API. It is very important
to note that variables are not shared between threads, all variables are per
default thread local. To use shared variables one must use threads::shared.

It is also important to note that you preferebly enable threads by doing
C<use threads> as early as possible and it is not possible to enable threading
by in an eval ""; 

=over

=item new, function, LIST

This will create a new thread with the entry point function and give
it LIST as parameters.  It will return the corresponding threads
object.

create is an alias to new

=item $thread->join

This will wait for the corresponding thread to join. When it finishes join will return the return values of the root function.
If a thread has been detached, join will return without wait.

=item $thread->detach

Will throw away the return value from the thread and make non joinable

=item threads->self

This will return the object for the current thread.

=item $thread->tid

This will return the id of the thread.
threads->self->tid() is a quick way to get current thread id
