Assuming we use GNU gettext, it'd consume virtual memory but not as much 
physical memory, as GNU gettext mmaps the message catalog (using PROT_READ so 
that it's read-only and the physical data can be shared). Only pages containing 
actual translations should need to be brought into physical memory (along with 
the indexes to these pages).

The total amount of virtual memory would depend on the catalog size. A 
reasonable upper bound for current Emacs master would be 61 MB (the sum of sizes 
of all of Emacs's .el files). Although 61 MB is nontrivial, there should be 
little trouble fitting it into virtual memory even on a 32-bit platform.
