Help -- how can I make the Apache process die at the end of the request?

[Victor Danilchenko <vi...@askonline.net>]

	I need to do it forcibly, no matter what happens during the request. I 
have to slightly relax security constraints to call an unusual 
subrequest, and since I cannot guarantee that the cleanup code will be 
reached (what if the subrequest is terminated by the client, or dies on 
a bug?), I figure my best bet it to make sure that at the end of the 
request execution, the current apache process dies so that a new one can 
be spawned. 'kill $$' is obviously inadequate.

	Does anyone have any idea how this can be achieved? perhaps utilizing 
MaxRequestsPerChild somehow, I could trick the parent process into 
terminating this one after the request completes? or is there some 
mod_perl feature which tells mod_perl to not re-use the perl runtime in 
a given process?

	Any help and/or ideas are much appreciated. Thanks in advance.

	Perfect. Much thanks.
