Yeah that's what I kind of meant by the engine support. :) My idea was more
about when it should be preloaded. For example one option would be to
preload it automatically if nothing has been preloaded as part of
php_execute_script / zend_execute_script. However that would mean to do it
for each child (basically use it for all request for the child process
life). It should work and might be a viable options for the initial
implementation but more optimal would be do it once for all children
running in the same pool which could be doable using the pool managers. I
think it would be great to have some kind of API so the SAPI can explicitly
preload the script.

Cheers
