running code asynchronously

[rjk-2]

Dear Seasiders,

I'm cooking up some seaside/code recipes as an exercise and hopefully
for (web)publication some day, i have the following question;

Q. How do i run code asynchronously (inside the request/response  
cycle) ?
A. My answer at this point is the following using a [block] fork.  
construct
as described in Smalltalk by example from alex sharp:

        01 renderContentOn: html
        02    html paragraph: Time now asTimeStamp.
        03    [Transcript cr; show: 'waiting for 10 seconds...'.
        04    (Delay forSeconds: 10) wait.
        05    Transcript cr; show: 'done!...'] fork.
        06    html paragraph: Time now asTimeStamp.

Could somebody confirm this? and give additional comments if this is  
not the true seaside way?
Thanks in advance!

The question sounds wrong :-D

IMO, it's either "synchronously inside the cycle" or "asynchronously
beside the cycle".

re "true seaside way": That would totally depend on what you're doing
in the forked thread.

- What problem do you want to solve?
- Whatever you do are you sure you want to do it in the rendering phase?
