Can someone please tell me why following script hangs. Main thread creates a thread (say "secondThread"). secondThread tries to create a thirdThread after sleeping for a while and that is where it hangs (i mean thirdThread is never created). Interesting thing is when main main thread prints something after I enter something on console the thirdThread is created. I am using ActiveState perl 5 on Windows (tried on XP and 7). 

#!perl -w
use strict;
use threads;
use Thread;
use threads::shared;

        
        
sub thirdThread
{
    threads->detach();
    printf "[%d] Third thread started\n",threads->tid();
}
sub secondThread
{
    threads->detach();
    while(1)
    {
        sleep 2;
        printf "[%d] Going to start a new thread\n",threads->tid();
        threads->create(\&thirdThread);   
    }
}
 
threads->create(\&secondThread);        
while(<STDIN>)
{
    print "CMD: ",$_,"\n";
    if($_ eq "quit\n")
    {
        last;
    }
}
