I can easily make your code work, just by adding a Timeout to your socket, which you should have any way. A server socket without timeout can run into many problems. Other than the problem you demo'd here, it could also become a dead socket (a socket that cannot be awakened by accept()), if you leave it idle for long enough.

use strict;
use warnings;

use IO::Socket::INET;

$|=1;

my $server = IO::Socket::INET->new( 
   Proto => 'TCP', 
   LocalPort => 2500, 
   Reuse => 1, 
   Listen => 10,
Timeout=>1
);

if (fork() == 0) {
   print("$$: Child 1.$/");
   $server->accept();
} else {
   sleep(1);   # Make sure accept is reached.
   if (fork() == 0) {  # <------ Doesn't returns until accept returns.
      print("$$: Child 2.$/");
      sleep(3);
   } else {
      print("$$: Parent.$/");
      sleep(3);
   }
}

print("$$: oye.$/");
