I'm using the following code to create client/server session. 
my($client, $client_addr) = $server->accept();

I've noticed that if the client is abruptly disconneced that the server will crash when $client->send() is called. How can I be sure that the client is still valid before the $client->send() command is issued? Just checking that $client still exists isn't enough, it seems to exist long enough after a disconnect to cause problems. 
#only send if $client exists
$client->send() if $client;
