It's partly historical. When I did an initial 'proof of
concept' I cached to files as this was the most
straightforward thing to do. Then I experimented with 
different schemes for loading the files, found that they
performed all pretty much the same, but that things would
be much faster if I executed directly from the shm cache
rather than simply restoring compiled code from the cache. 
No one other than Zend was doing this, and so I then added
support for that.

Unless you want acceleration from the CGI PHP. Some weeks
ago I was about to abandon SHM support for the cgi 
version and do what you suggest, but by chance someone
emailed who was making use of the cgi version and 
that made me rethink the decision.  It could consider
making this a configuration option.

Cheers
