I wonder whether one should also do what Joost has proposed:* Changing 
"allocatable" to "al" etc. That reduces both the .mod file size (and 
thus I/O and improves caching) and the memory consumption of the 
compiler with the proposed caching scheme. As context-aware compression, 
it could even have a better ratio than ZIP. (ZIP can still be used on 
top of it.)
