While handling TERM signal, I am trying to set a flag and also ignoring the TERM signal. But sleep breaks if the TERM signal is issued to this process. 
$SIG{TERM} = sub {$SIG{TERM}="IGNORE";
                  $term_sig = 1;};
print "\n  $$ \n";
sleep(20);
print "TERM signal ignored\n";

Code to issue TERM signal 
kill -15 <pid>

Please help me in understanding why the sleep breaks even though TERM is handled.
