And given that they can be very very large that is a serious problem. I don't think PL_sawampersand is as useless as some people thought it was. It would involve uncomfortable chumminess with core internals, but could the problem with File::Map be solved if the mapped file was exposed as a (SVf_IsCOW|SVppv_STATIC) type of COW? No idea if the regex engine can operate on those though...
