From Promise

(Promise) method in

method in(Promise:U: $seconds:$scheduler = $*SCHEDULER --> Promise:D)

Creates a new Promise that will be kept in $seconds seconds, or later.

my $proc ='perl6''-e''sleep 10; warn "end"');
my $result = await Promise.anyof(
    my $promise = $proc.start, { note 'timeout'$proc.kill }
).then: {$promise.result};
# OUTPUT: «timeout␤» 

$seconds can be fractional or negative. Negative values are treated as 0 (i.e. keeping the returned Promise right away).
