I might be wrong with the resulting conclusion, yet it seems to me it 
should work.  In order to start an httpd instance this way, it would 
still require inets to be started.  Given that if you make your custom 
application that owns the httpd instance dependent on inets (i.e. 
include inets in the 'applications' section of the *.app file), wouldn't 
release handler be able to do a soft upgrade of inets by restarting your 
custom app together with the httpd instance?  Or this wouldn't classify 
as a truly soft upgrade?
