Huh?

I have some small programs with one thousand lines in the main source  
and using units with about 30k loc. Recompile and linking the program  
takes less than a second.
The main work is spent in loading the ppus and of course the gnu slow linker.
I'm confident that a compiler kept in memory reusing the parsed ppus  
should be able to compile even medium sized LCL projects in less than  
a second.
Of course linking and writing a 20mb exe with debugging information to  
disk will take some time.
