Continue session that is "delay"-ed?

Hi,

when I have one session delayed like so:

...

my $wait = 5;

$kernel->delay(post_query => $wait);

...


And I want to short-cut that delay (i.e. continue to event "post_query" 
now instead of waiting until the 5 seconds are done) from another 
session, how can I do that? I do have the delayed session's alias, but 
how do I signal that session to go on?
Thanks in advance,

Bas.
