I'd agree with that.

No.  (Well, not straight-forwardly, anyway.)  Apache::Symbol is not a 
simple Apache-savvy replacement for Symbol -- it is quite a different beast.

The patch uses Apache::Symbol::undef_functions(), which wraps calls to 
Apache::Symbol::undef().  Neither of these functions are in Symbol, so 
I'd have to copy them from Apache::Symbol into Apache::Reload itself. 
 (And that's more work than it sounds because undef() is an XSUB.)

Would it not be simpler to put Apache::Symbol back into mp2?
