[gforth] keeping code and data in the same segment

[Joel Reymont]

I heard that gforth is 2x faster than swiftforth on Mac OSX because sf  
keeps code and data in the same segment. This, apparently, results in  
a flush of the instruction cache whenever data gets written.

Since gforth is just as self-modifying as sf, how does gforth work  
around this issue?

Does gforth keep code and data separate?

        Thanks, Joel
