Odd, I'm on 5.8.8 and don't seem to be seeing the same behaviour:

$ perl sigdie.pl &
[1] 14327

$  ps -Fp 14327
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
cwright  14327  1335 99  1097  1436   0 12:01 pts/11   00:00:08 perl sigdie.pl

...

$  ps -Fp 14327
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
cwright  14327  1335 98  1097  1436   0 12:01 pts/11   00:00:53 perl sigdie.pl


Oooh, but interestingly, if I chmod the script and run it:

$ chmod 0755 sigdie.pl
$ ./sigdie.pl &
[1] 14421
$  ps -Fp 14421
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
cwright  14421  1335 94  3404 10384   0 12:03 pts/11   00:00:06 /usr/bin/perl ./sigdie.pl

...

$  ps -Fp 14421
UID        PID  PPID  C    SZ   RSS PSR STIME TTY          TIME CMD
cwright  14421  1335 98 12863 48308   0 12:03 pts/11   00:00:35 /usr/bin/perl ./sigdie.pl

  You're the font of all knowledge?
  It's just a shame someone pulled the plug.
