Reduce the size of each ClientPage entry point from 64-bit pointer to 32-bit integer offset, to facilitate increasing the number of free ClientPages Store ClientPage and TranslationCacheFragment objects contiguously Increase transation cache and ClientPage cache proportional to client memory, existing defaults result in a large amount of thrashing with OS X 10.4.11 client Limit translation cache to 2GB so that jmp/call within the translation cache can use 32-bit relative instructions Implement a jump table for jumps from the translation cache to asm functions in the text segment. This is placed at the beginning of the translation cache so it can be reached with a 32-bit relative jump This resolves the immediate segfault when running a gcc compiled elf on Linux, as the elf is observed loading above the 64GB address mark
