I'm not for this idea as I think it opens up the door to more sequencing usage style of faux bugs.

Take a look at library.rb for #attach_function and #attach_variable and see how they might work with additive #ffi_lib intermingled with calls to each.  Don't know if anyone would actually code that way, but...

What's the value add you see for an additive ffi_lib?
