It should be easy to implement the same behavior we have with Zend Debugger
today also with Xdebug.  The debugger essentially intercepts the compile()
callback before Optimizer+, and if it determines that the present request
should run through the debugger - it bypasses the Optimizer+ altogether and
calls directly into zend_compile_file().  I'll update the RFC that it should
be possible to integrate it nicely with any other modules.
