Yuck, are you secretly advocating making all your variables global?
use warnings;
$x;
my $y;

Useless use of a variable in void context at e:\scripts\undec.pl line 2.
Name "main::x" used only once: possible typo at e:\scripts\undec.pl line 2.

Use alarm to send yourself a SIGALRM in $timeout seconds, then install
a function that handles SIGALRM.
This is a frequently asked question. You can use
perldoc -q keyword
to search the Perl FAQ for the given keyword; in this case,
perldoc -q timeout
would have given you the answer you are looking for. See also:
perldoc -f alarm
perldoc perlipc
Cheers,
Rick
