The way glibc and some distros have implemented locales makes mlockall() quite useless for many purposes now in practice IMHO. We discussed the options at the time and wrote the extra code to implement the only solution we were offered. (1) There was no possibility of some distros not using a single locale database (reasons: optimisation and packaging convenience); (2) there was no possibility of glibc providing a mechanism to unmap the locale database (if you reset your locale to the default glibc will not unmap the file and indeed doesn't rule out doing something similar with other files in future - these are glibc internals and it's none of our business).
