I have - it's what I was referring to when I mentioned PHP worker process
trickery. I know it can be done, but it isn't straightforward and it can't
be quickly applied to existing applications like Wordpress or Drupal.

I know. What I'm wondering though is, could there be a way to do this on
the PHP engine level that would avoid massive rewrites of existing PHP code=
.

Here's my current draft of a way to implement this using two statements.

require_bootstrap( [FILE] );

This statement loads and executes the code in question just as require
does. It saves the execution state before moving to the next code line
after this statement is called. If called without a file it saves the
execution state immediately.

The saved execution state is hostname aware for sites that use a multisite
configuration.  So if the statement is reached from
www.onesite.com/index.php and from www.twosite.com/index.php two different
bootstraps will be created. This is done on the assumption that the booting
process is going to make one or more decisions based on the hostname.
Drupal loads entirely different setting files, module lists, uses a
different Dependency Injector, all according to the hostname.

unload_bootstrap( [PATH] );

This unloads the bootstrap associated with the webpath given. If no
argument is given the current bootstrap image is dropped. Question - should
passing boolean TRUE unload all the bootstraps at once, or should that be
it's own function, or is it necessary?

Note that bootstraps will be unloaded automatically if the opcode cache for
the associated files changes.


Thoughts, suggestions, questions, complains, or flames?
