That's fine by me, and in fact very close to the solution I  
implemented in "engines/scumm/string.cpp" for the _languageBuffer/ 
_languageIndex (see loadLanguageBundle). Load pred.dic into a global  
buffer, replac some spaces/newlines by zeros here and there, then  
keep one big array of pointers pointing to the start of each word.  
This saves memory, reduces the number of malloc operations greatly,  
and should have a comparable speed.

However, I am deeply concerned that we make such a big change on the  
brink of a release. Hence I propose that we delay the release again  
until the coming weekend to be able to properly test this.

Bye,
